Another note: Have a lender friend who is a LS vendor and she has not gotten a lot of business from the LS members.

Well who said running a business is easy?

Either way is not good for your business.

@James MeyerAs a realtor you would be classified as self-employed and therefore eligible to sponsor a Solo 401(k) - assuming you do not own or control any other business that has employees.Your employee deferrals are capped at $23,000, or $30,500 if you are over age 50, across all plans you participate in. 

My profile has more information about the contracting business. 

Second issue is that “wholesaling” as the term is used now is NOT investing; at the low level operation it’s a JOB as an unlicensed real estate broker; at the high level it running a FULL BUSINESS operation.  

Since this is not only your business but you say you've taken money from banks and investors you might want to take some time to learn about the licensing and zoning requirements.

It looks like you have a business loss which you can use to offset other forms of income.I don't think you sold it less than its worth, you likely tried to get as much as you can.Squatters decrease the value of a home, especially if you are selling the house with them in it.

I would advise you not to use this as a launch pad for your real estate investment business if you aren't well capitalized.

This entails dedicating a significant amount of time and effort to the short-term rental business.
