OPINION BY FREEDBERG, J.:

Appellant, ATL Ventures ("ATL"), as third party purchaser, appeals from the August 17, 2009 orders of the Court of Common Pleas of Chester County, which denied ATL's amended petition to set aside the sheriff's sale, and ATL's motion for reconsideration. For the reasons discussed below, we affirm.

The relevant facts of this matter are taken from the trial court's November 2, 2009 Opinion. On May 29, 2002, first mortgage holder GE Capital Mortgage ("GE") filed a complaint in mortgage foreclosure on the property known as parcel number 15-9-37, 5th Ward, Phoenixville Boro, Chester County, Pennsylvania. George and Nancy Famous ("the Famouses") are the owners of the property. On June 19, 2008, second mortgage holder Irwin Union National Bank & Trust Company ("Irwin Union") filed a complaint in mortgage foreclosure. Irwin Union obtained a default judgment and assessment of damages. ATL purchased the property at a January 15, 2009 sheriff's sale on Irwin Union's judgment for $25,100.00.

On March 12, 2009, ATL filed a petition to set aside the sheriff's sale of January 15, 2009. Irwin Union filed a response on March 20, 2009. ATL filed an amended petition to set aside the sheriff's sale on April 2, 2009. By Order dated April 16, 2009, the trial court continued a scheduled sheriff's sale in GE's foreclosure action against the Famouses to June 18, 2009. The same order gave ATL thirty (30) days to conduct discovery on its petition to set aside the sheriff's sale.

On August 17, 2009, after argument, the trial court denied ATL's petition to set aside the sheriff's sale. On August 20, 2009, GE purchased the property at a sheriff's sale conducted as a result of its foreclosure action. On August 27, 2009, ATL filed a motion for reconsideration, which was denied by Order of September 2, 2009. ATL filed a timely appeal and was ordered to file a concise statement of errors complained of on appeal pursuant to Pa.R.A.P. 1925(b). Appellant timely filed the 1925(b) statement, and the trial court issued an opinion.

On appeal, ATL raises the following issues1 for our review:

ATL's Brief at 2.

Pennsylvania Rule of Civil Procedure 31322 provides:

Thus, the relevant inquiry is whether proper cause has been shown to set aside the sheriff's sale. The decision to set aside a sheriff's sale is within the sound discretion of the trial court. Merrill Lynch Mortgage Capital v. Steele, 859 A.2d 788, 791 (Pa.Super.2004), appeal denied, 582 Pa. 718, 872 A.2d 1199 (2005) (table). A petition to set aside a sheriff's sale is based on equitable principles. National Penn Bank v. Shaffer, 448 Pa.Super. 496, 672 A.2d 326, 329 (1996). "The burden of proving circumstances warranting the exercise of the court's equitable powers is on the petitioner, and the request to set aside a sheriff's sale may be refused due to insufficient proof to support the allegations in the petition." Kaib v. Smith, 454 Pa.Super. 67, 684 A.2d 630, 631 (1996) (internal citations omitted). Sheriff's sales have been set aside where the validity of the sale proceedings is challenged, a deficiency pertaining to the notice of the sale exists, or where misconduct occurs in the bidding process. Blue Ball National Bank v. Balmer, 810 A.2d 164, 167 (Pa.Super.2002), appeal denied, 573 Pa. 662, 820 A.2d 702 (2003) (table). This court will not reverse the trial court's decision absent a clear abuse of discretion. Kaib, supra.

ATL claims that the trial court erred by failing to allow full discovery in this matter, so that it could more fully develop its claim that custom in Chester County required Irwin Union to disclose the existence of a first mortgage on the property. The April 16, 2009 Order in this matter allowed thirty (30) days for discovery. The record reflects that ATL served several sets of interrogatories. On June 16, 2009, ATL filed a motion to compel further answers to the interrogatories from Irwin Union. For reasons that are not apparent from the record, the motion to compel was not ruled upon.

Pennsylvania Rule of Civil Procedure 4003.1(a) provides for the scope of discovery as follows:

Appellant contends that the thirty (30) day time period in which to conduct discovery was inadequate and, because of this, it was unable to fully develop the record on this matter to establish a custom of announcement of the liens prior to the sheriff's sale.

ATL did not file a petition to extend the discovery period in this matter. Therefore, it cannot complain that the allotted time for discovery was too short.

Further, in the motion to compel, ATL does not specify the nature of the information sought; what specific interrogatories Irwin Union either declined to answer or did not fully answer; in what manner Irwin Union's responses were inadequate; and how the information sought was reasonably calculated to lead to the discovery of admissible evidence. ATL claims that it was unable to fully develop the record with respect to the contention that it was the custom at Chester County Sheriff's sales for the attorney for the foreclosing party to announce the existence of an encumbrance on the property. However, ATL does not explain in its argument how the responses impacted on its ability to prove that the custom was breached. This Court will not act as counsel and will not develop arguments on behalf of an appellant. Commonwealth v. Hardy, 918 A.2d 766, 771 (Pa.Super.2007), appeal denied, 596 Pa. 703, 940 A.2d 362 (2008) (table); Bombar v. West American Insurance Company, 932 A.2d 78, 94 (Pa.Super.2007). When deficiencies in a brief hinder our ability to conduct meaningful appellate review, we may dismiss the appeal entirely or find certain issues to be waived. Pa.R.A.P. 2101; Hardy, supra. It is not this Court's responsibility to comb through the record seeking the factual underpinnings of ATL's claim. Commonwealth v. Mulholland, 549 Pa. 634, 702 A.2d 1027, 1034 n. 5 (1997). Because ATL failed to clarify the specifics of its discovery claims, and further because it did not seek additional time for discovery, we find this claim to be waived. Pa.R.A.P. 302(a); Pa.R.A.P. 2119(e); Pa.R.A.P. 2101; Hardy, supra.

Finally, discovery is limited to that which is "relevant to the subject matter involved in the pending action." Pa.R.C.P. 4003.1(a). As will be developed infra, the existence of such a local custom is irrelevant to this case.

ATL also argues that it is entitled to a refund of the money it paid because it did not receive a deed to the property.3 Additionally, ATL claims that it was deprived of the money it advanced for the purchase price without due process of law in violation of the Fifth and Fourteenth Amendments of the United States Constitution. Irwin Union responds that these claims are waived because ATL raised them for the first time in its 1925(b) concise statement. In its reply brief, ATL concedes that the issues were raised for the first time in the 1925(b) statement but claims that the issues are not waived because they are matters of law.

It is well settled that issues not raised below cannot be advanced for the first time in a 1925(b) statement or on appeal. See Pa.R.A.P. 302(a) ("Issues not raised in the lower court are waived and cannot be raised for the first time on appeal."); Diamond Reo Truck Company v. Mid-Pacific Industries, Inc., 806 A.2d 423, 430 (Pa.Super.2002) (issues cannot be raised first in a 1925 statement). In support of its contention that it was not required to raise this issue below, ATL cites three cases: (1) Otte v. Covington TP. Road Sup'rs, 539 Pa. 44, 650 A.2d 412, 414 (1994); (2) Commonwealth v. Smith, 854 A.2d 597 (Pa.Super.2004); and (3) Jara v. Rexworks, Inc., 718 A.2d 788, 792 (Pa.Super.1998), appeal denied, 558 Pa. 620, 737 A.2d 743 (1999) (table). None are apposite. In Otte, the Pennsylvania Supreme Court held that the Commonwealth Court did not err in deciding a case on the merits where the trial court did not issue a 1925(a) opinion, as the case involved only "pure questions of law." Otte, supra. Nothing in Otte supports the view that a question of law raised for the first time in an appellant's 1925(b) concise statement must be decided on the merits by an appellate court. In Smith, this Court noted that, "[w]aiver is required when an ordered statement is not filed, but is discretionary with the trial court when the statement is belatedly filed." Id. at 599-600 (internal citation omitted) (emphasis added). There is no support in Smith for the proposition that waiver is discretionary when an appellant raises an issue for the first time in a 1925(b) statement. Lastly, Jara concerned the non-aggrieved party's not filing a cautionary post-trial motion, and in later decisions this Court specifically rejected the notion that Jara stood for the proposition that an issue raised for the first time in a 1925(b) statement was preserved for appellate review. See Chalkey v. Roush, 757 A.2d 972, 979 n. 6 (Pa.Super.2000), affirmed, 569 Pa. 462, 805 A.2d 491 (2002).

ATL's next claim is that the doctrine of caveat emptor should not be applied in this matter because Irwin Union was aware of the existence of the first mortgage but did not advise potential buyers of that fact. This Court has long held that:

Juniata Valley Bank v. Martin Oil Co., 736 A.2d 650 (Pa.Super.1999) (internal citation omitted).

ATL contends that there is a custom in Chester County of announcing the existence of encumbrances on the property at sheriff's sale. ATL does not cite any legal authority which supports the notion that local custom prevails, given the adoption of the doctrine of "caveat emptor" in the cases cited herein. ATL does not claim that Irwin Union was asked about, made representations about, or supplied misleading information about the existence of a first mortgage. ATL also does not aver that a title search would not have revealed the existence of a first mortgage.4

This Court has held that a purchaser's error in assuming that a sheriff's sale had the legal effect of discharging a first mortgage was not sufficient ground to set aside a sheriff's sale. National Penn Bank v. Shaffer, 672 A.2d at 330. In so holding, this Court stated:

Id. The Court also noted that courts have generally refused to award relief because of a party's unilateral mistake of law or fact. Id. at 331.

In support of its contention that equitable relief is appropriate in this matter, ATL cites Merrill Lynch Mortgage Capital v. Steele, 859 A.2d 788 (Pa.Super.2004). However, that case is factually inapposite. In Merrill Lynch, the property at question had been listed for sheriff's sale when a private party purchased the property the day before the sale. Id. at 789. The private purchaser had sent the mortgage payoff proceeds to the mortgage creditor before the sheriff's sale. Despite the private sale, the property was then sold to a different party at a sheriff's sale. The deed issued to the private party was recorded several hours after the sheriff's sale but before the sheriff's deed was issued to the buyer at the sheriff's sale. The private purchaser filed a timely petition to set aside the sheriff's sale, which was denied by the trial court because of a lack of standing and, in the alternative, because the petition failed to set forth sufficient grounds to set aside the sale. Id. at 790. This Court reversed, finding that the private purchaser who purchased the property prior to sheriff's sale was a bona fide innocent purchaser for value, whereas the party who purchased the property at sheriff's sale knew that there was the possibility that the sale could be set aside in accordance with Pa.R.C.P. 3132. Id. at 792.

ATL does not dispute Irwin Union's claim that ATL regularly buys properties at sheriff's sale and, thus, is acquainted with the risks associated with such a purchase. There was nothing which prevented ATL from conducting a title search prior to purchase which would have revealed the existence of the first mortgage lien on the property. The cases ATL relies on for support of the view that equitable considerations require that it be granted relief are all from the early part of the twentieth century. We have specifically disavowed reliance on such cases, noting that "... [t]he difficulties and expense of ascertaining the state of a title ... have been substantially reduced by the advent of advanced information technology. Equitable considerations therefore no longer favor the protection of purchasers to the extent necessary [in earlier cases]." National Penn Bank v. Shaffer, 672 A.2d at 329-30.

ATL's final claim is that there were "important substantive issues" that the trial court should have decided rather than relying on the "caveat emptor" principle. Those issues are: (1) the price ATL bid for the property in question is inadequate; (2) Irwin Union did not give the Famouses proper notice of their right to stop or prevent the sheriff's sale; (3) the property description in the sheriff's handbills is incorrect; and (4) the underlying mortgage was a "toxic mortgage" and, therefore, void as against public policy.

"[A] party seeking judicial resolution of a controversy in this Commonwealth must, as a prerequisite, establish that he has standing to maintain the action." Merrill Lynch Mortgage Capital v. Steele, 859 A.2d at 789-90 (internal citation omitted). "A party has standing if he is aggrieved, i.e., he can show a substantial, direct, and immediate interest in the outcome[.]" Id. at 790.

ATL has not shown that it was aggrieved by paying an "inadequate" price for the property. Further, it is well established that mere inadequacy of the sale price of real estate is not a sufficient ground for setting aside a sheriff's sale; rather the price must be "grossly inadequate," a claim not made by ATL. S & T Bank by Dalessio v. Dalessio, 429 Pa.Super. 282, 632 A.2d 566, 569 (1993).

ATL has not established how it was aggrieved by the allegedly inadequate notice sent to the Famouses. Therefore, ATL lacks standing to contest this issue.

Irwin Union concedes that the house number of the property is listed incorrectly in the sheriff's handbills. However, ATL does not claim that this caused any confusion, that it bid on the wrong property, or that this in any way affected the sheriff's sale. Thus, the contention lacks merit.

ATL has further failed to provide any legal support for a claim that a "toxic mortgage" is a ground for setting aside a sheriff's sale. In its brief, ATL acknowledges that the term "toxic mortgage" is not a legal term, but rather a term coined by the media, economists, and finance experts to describe certain financially dubious mortgages. ATL's Brief at 16. ATL also admits that it has no direct knowledge of whether the mortgage in the instant matter was "toxic." Accordingly, there is no merit to this contention.

Order AFFIRMED. Jurisdiction RELINQUISHED.
