Make sure they have great credit so you know you can go after them for damages.

My partner and I have an investor that has a line of credit on his house.

Please read and learn about the velocity of money to prepare your mindset. 

All credit is due to what ive learned here, from you guys!

I am wondering if something similar exists for a commercial property as well.All thoughts and suggestions welcome.Thanks,Piku Yes, it’s just called Just the line of credit. 

I only have fair credit, 700, how can I get a loan to buy my first property, when of course, I find it? 

In other words, if they have no proof, but you do, then you win as most states have landlord/tenant law that favors the tenant.As was stated above, keep your small claims court date and be prepared to take your proof, as well as a VERY detailed account of everything you can remember from conversations and other occurrences between you and the landlord, or the landlord's rep, to court with you.In Colorado, for example, the landlord must return the deposit in full, or issue a check and a detailed statement covering the amounts not returned, within 30 days. 

I have excellent credit, zero debt, and a decent amount of cash in the bank.

I learned something new and I'll be better prepared in case I see these in some future pool. 

No sorry it is not in my plans for the forseeable future.Alternately you could suggest you will have the work done by qualified contractors if he is prepared to pay for it.
