It is probably 10yrs behind on remodels so would need some interior design work, possibly just a wall or two knocked down.

Or, if I was going to remodel the unit, or replace the floor regardless of the damage and just because it is old I would not charge a penny.I am quite a bit on the soft side when tenants cause damage and it depends on how the tenant treated my staff and myself.

Purchase price: $85,000 Cash invested: $40,000 Very rough 3 unit, remodeling now, 40k is an estimate for now.

Adding a bathroom to it in the Complete gut remodel.

Remodeled new floors in the entire house.

I know that there are two online resources, local to Houston, that offer some good online estimating tools:Brant Phillips had one at point, but I don't see a link to it now... but I do know that Fast Track Remodeling has one on their site.  

Same can be applied for remodels / rehabs.

My husband owns a construction company and remodels rental properties for investors.

I totally remodelled kitchen, both baths, and finished the basement, adding significant living area.

I remodeled it to move in to, but ended up renting it out and here we are.
