.: @Chris Core - you will not find cash flow in Huntsville right now unless you want a C/D neighborhood property (not all of those work right now either) or you want to put over 30% percent down on a purchase to "force" cash flow. 

I love that you’re already narrowing down specific zip codes and doing your due diligence.I’ve heard good things about 73170 and 73135, especially with the proximity to Tinker Air Force Base, which tends to attract stable tenants.

You’ll either need to focus on high-cash-flow opportunities or equity-building plays (forced appreciation in value-add properties.

If worse comes to worse and I need to get a judgement against the tenant and co-signer(s) can I force them to pay?!?

There's no statutory or common law basis to force the builder to provide plans.

Quote from @Scott Mac: Can the staff force you to do that or hold you up in some way?

Being a subject matter expert, not because you are forcing it, but because you simply ARE, shows through, and investors are rightfully attracted to that. 

You can't "force" your way in, but there's no law stopping you from knocking on their door to ask if you can check the furnace/ac unit out.4) Don't escalate as they have possession of your property and to can bad things to it!

We finally had to have the police go there and we forced the door open with this mom screaming and crying all day at us as we replaced 8 windows.

Clearly identify what you want to achieve in real estate and use that as a guiding force throughout your journey.
