I have no clue what to do with it.

See if you can get a viable co-borrower to sign with you.Boom, problem solved until you develope more in the future.

If flakes that contain lead is not abated (disposed) properly, you are not really solving the problem but just spreading your problem, EPA might make you remove all the dirt amd dispose them on an accredited landfill for hazardous materials.

If it's a problem that occurs once or twice with some individuals, it may be on them, but if it repeatedly comes up in your business, it is likely to be a failure on your part to solve the problem.

@Derrick RI think having a license and solving problems for home sellers, showing them all their options, but "acting as a principal OR as an agent" is the way to go.You can list a thin equity pretty house deal for cash and make a commission.You can list a thin equity pretty house deal for terms like a lease w option or a lease purchase or a land contract and make a commission.You can act as a principal and assign a contract (lease option, lease purchase, sale and purchase, etc) for a fee.You can close and get on title and resell as a principal. 

Solves any issues unless you put something under contract with no ability to close.
