I’d like to raise rent slightly because I know for a fact property taxes in Texas are going up since the house appreciated 90-100k in the last year. 

@Rami Holzman  Covered above, no lender is going to do that as they'll require a personal guarantee from you.Best bet is to open a few secured credit cards, pay them on time and in a year you should have a decent credit score. 

AKA very easy/simple things that require no actual part replacements or major work.My fear is that when I hand my portfolio over to a PM I will be getting a lot of high price maintenance expenses for service calls which might raise my expenses dramatically.

Raise the rate up and you get lender credit to cover closing costs. 

Postal Service address,Voter Registration Card,Federal and state tax returns, andDriver's license or car registration.The home is near:Where you work,Where you bank,The residence of one or more family members, andRecreational clubs or religious organizations of which you are a member."

I can probably raise it a little.

Call the agency and just say “I am looking to raise the rent by 10% and add a $35 water bill how exactly do I do that through you guys?

Why don't you raise the rent a little each year to get closer to market rent? 

If it is a case that they are older and not energy efficient, I doubt it plus flags would have been raised when you had the place inspected at the time of purchase.

Raise rents andbuild to protect market.Interestrates- let's say 4%, I can only see them going up.Supply Chain- Steel from China is fighting to get through the same ships and portsalong with toys.CargoContainers- You can’t buy a used container now.
