Garage Conversion Cost

[Mike Hong]

The house I am planning to buy has a detached 2-car garage (20x26=520 sqft). It has a concert slab and already has electricity. If I want to turn it into a 1-bedroom apartment, how much would it cost? I just want to rent that place out to help pay for mortgage. I am in Oklahoma City. Any advice would be much appreciated!!

I'm a builder and I would suggest you first check with your HOA if you have one then with your city permit office.
To get better pricing you should drive by construction site and ask the different trades for their number. Tell them you are an investor not a homeowner. These trades work predominantly with general contractors and builders so their pricing is lower than those who provide their services to homeowners.

Another thing you can do is provide the materials and have the trades provide you quote on labor. 
Best of Luck
