Adding a couple of clean outs on new pipe should be no big deal. 

I'd likely just agree to break the lease with a couple months of rent as a penalty rather than force these people to continue being tenants in my property....you never know what will happen to the condition of the property.

I prefer to not hire an attorney unless I must because I am afraid it will cost a lot of money.

Speak with couple hard money lender there are plenty lenders that are local and knows the market.

The higher credit is attractive, but what if the couple's income is 3.2x the monthly rent and the single woman makes 6x the rent?

@Daniel Kazakos Correct, I don't think I could qualify as a RE Prof in the next couple of months given that 750 hours is required and nov and dec are "short" months. 

Usually all you need is a couple really good comps to know how your property would do and that is easier to find with a paid version of Airdna. 

I know a couple of the Realtors on the team at Suncoast Property Management, Acquisitions & New Construction Manager, Gretchen Kornutik, REALTOR® - Good person.

Most are performing well and a couple of them are in the middle of dealing with evictions. 

As a married couple, you can also take advantage of the $500k capital gain exemption.
