Most settle before that (either agree on prolong stay or reduce the rent owe or both).

Valuations of property or services don't come from thin air! 

Here's our big ticket checklistRoof conditionExterior wall conditionExterior Deck conditionWalls- Plaster or Drywall (We usually replace plaster if the property has to be updated)Electric updated or not;  Plumbing updated or notMechanical Systems-  HVAC- Boiler or Forced Air (We prefer the systems be separated where the tenant will pay for their own heating & cooling, but many of the older properties in the area are boilers where the owner pays for heating)  See if you can determine the age of mechanicalsEverything else is cosmetic.  

Other than I fly into the airport just n. of town and the one over at Courdelene   as well as the one up on the big lake north.. so I know it from the air  LOL.  

My parents are Air Force vets. :)

I'd look in areas such as The Village, Midwest city,  and Del City near Tinker Air Force base, and some areas near downtown.  

This area is great as there is a university and the Air Force base that will attract tenants, but you'll have to be patient to find the right deal. 

Per the seller, the property is a fixer upper, no central air or heat only window unit.

I'm currently employed as a welder at a local shipyard, and I also serve in the Air Force Reserve.I have always wanted to pursue a career in real estate, but honestly I was scared of the risk.

We installed central air and the bonus room, but never did any flooring (didn't need to).
