I would keep the property, take the extra cash flow & invest in more rentals/real estate strategies. maybe start another business. never sell the house unless i absolutely have to. 

Can you use a  private investor and use a  JV?

I've sent you a private message.

I read the business news to find out about new developments.

So I got a private message from @Peter Walther to the effect that he was not allowed to comment on this thread.Do you really need to be a Pro/Premium member to comment on posts?

I would consider the business uses of your home, the basement apartment is considered a rental property if you rent it out.

Some tenants will shape up if they see the new owner means business (paying rent on time, etc.), so it's important to enforce rental agreements when you take over. 

Once you see that a company offers such a guarantee, check the Better Business Bureau to see whether consumers complain that the company hasn’t followed through on that promise.Expectations should vary based on the duration of the programs as well.

So far, I've managed to build a really good team to support my business from agents and contractors to wholesalers and lenders.

The private lender interest rates are high.
