How much would adding a full bath affect the ARV?

[Ryan Nodurft]

I am about to close on a 1300sf 4/1 single family in Watson that I am rehabbing to rent. I am trying to get the ARV up as much as make sense for a rental, to refi and get back what I put in.

I believe the ARV will be around 125k after some minor repair and cosmetic work. My contractor is quoting $6,800 to add a full bath and closets in the master, changing it from a 4/1 to a 4/2. Obviously this would increase the appraisal, but I am wondering how much? Would I recoup the investment?

Also, I think I could get $1150 rent as a 4/1, but could probably get $1300 as a 4/2. Does this sound correct?
