I would start with seriously reviewing the state statute then your local city laws.

@Cody Wageman:You may need to review the LLC statutes of whichever state you are incorporated in to know what an LLC (or any other entity for that matter) is authorized to do as it pertains to lending. 

Hi Hyeseong:"Pennsylvania has a statute prohibiting prepayment penalties on residential mortgage loans (apparently only those under $50,000 on one- to two-family property) (41 P.S. § 101, 405) and another statute prohibiting them altogether on loans made by second mortgage licensees (7 P.S. 6612)."

There's an express statute that says wholesaling is legal;An appellate court has expressly ruled that wholesaling is legal (although you have to be careful from overreading an appellate decision); and/orThe relevant regulatory agency for the jurisdiction has expressly stated that they consider wholesaling to be legal (and they haven't changed their mind since).

My recommendation is to read the landlord tenant guide booklet for the state statute regarding this and get into compliance.

If you file suit, look for a Statute or Procedural rule allowing for an expedited action; if you have suit filed against you, make the case complex for them and with potential negative consequences such as highly $$ counter-claims.In Texas, Rule 169 of the Texas Rules of Civil Procedure which provides for a trial within 9 months or sooner.

All of the answers will be located in the county rules and regulations and in the statutes for the District Of Columbia.
