When you start "picking" tenants or doing favors or acts of kindness for tenants is really when you can get yourself in legal trouble. 

But remember that what is favorable now could come unfavorable in the future as they readjust over time.Reasons many landlords avoid vouchers include the hassle of the extra inspections, the perception of a worse tenant, and maybe the inconvenience of getting rent from two different parties. 

First, it is necessary to achieve favorable financing terms and  secondly, I do believe cash flow should carry most rental properties with limited exceptions.

Sometimes friends/family will give you a favorable rate so it might be worth asking. 

I briefly considered signing my STR over to an arbitrage group last year under much less favorable terms last year.If this suites you it may be advantageous.

It could be a single family as well, but with your cash position it seems favorable to go a little bigger.

This is a big legal issue that may weigh in favor of the investor. 

The judge granted a judgment for eviction in my favor and I then filed a writ or restitution.

I am HUGELY in favor of treating tenants like people, but that doesn't mean I need to think of the relationship as personal.

It’s a good idea to review local real estate development compensation norms or even consult with a lawyer to ensure the deal is fair.In your uncle’s case, the terms seem fairly favorable to the engineer if he is only handling the development and not contributing any capital.
