Who's security deposit does the wall repair come out of? 

@Henley H.Not sure where you are and what is customary for the area but you’re knowingly entering into a lease with someone who is low on cash reserves if they don’t have first, last and security.

Also the auction time from is short, often too short to secure a loan. 

First, any security deposit he has, could likely be shifted to down payment at closing. 

The loan is secured against your home, but used to buy a rental property.

This is a security measure to ensure that people can control which apps can make payments from their bank account. 

They ultimately declined our offer and chose to move elsewhere.I requested a forwarding address from them and they eagerly questioned me about the security deposit being returned.

You can also invest out of state and try to secure a multi-family property that way.

Do you have a weight limit on dogs to keep the potential "dangerous" breeds away, or do you find that most folks don't travel with their 100 lb Rotty?

Once done and if your the most qualified tenant then I would rent to you.Maybe you voluntarily offer to pay additional rent or animal fee to show you are not trying to game the system or at least offer to pay a higher security deposit which you would get back if you take care of the property.You are not being fair by assuming everyone is discriminating against you with no proof.
