I'm trying to figure out if I can get the consistency in MTR for the price I need to cover the mortgage. 

Might I suggest a separate addendum with regards to the septic system that ALL adults sign and covers what you want them to know.

Ultimately we decided that the cost of doing the cost segregations right now was not beneficial enough since he didn't really have any reason to pay for them and if I would have covered the full cost then the benefit wouldn't have been significant enough to me.That said, I do know there are ways to structure your operating agreement where the depreciation can be distributed to different partners in different ways.

That should cover any overages that the STR insurance doesn't.

A financial advisor can help you  create a comprehensive financial plan to make sure you cover all your bases before you move forward. 

Keep in mind that there may be legit charges associated with termination- for instance, they may need to hold some funds in escrow to cover lingering utility bills or cleaning after that 30 day period. 

You should have an umbrella policy to cover everything, beyond maximum liability coverages.

I've never had a problem, so I'm not sure exactly what they cover or the terms.

I agree with my property manager that this is a reasonable ratio, because the co-signer need to cover their own house spending as well.

It’s a good way to cover your living expenses and build equity while you learn the ropes.
