Now comes the time I have to start organizing my interior repairs with the insurance settlement money.

That would depend on initial condition, but to add HVAC, upgrade all finishes, redo plumbing, electrical, paint exterior and interior, exterior upgrades and landscaping - ended up being at least $25k per unit. 

Now comes the time I have to start organizing my interior repairs with the insurance settlement money.

There are a few interior doors missing.There is a small bedroom that was being converted to a master bath, and right now it is completely gutted down to bare studs.

The property likely needs about 60k of interior fixing, but it looks presentable from the street.

Interior is basically done and I still need to paint and do some minor exterior work.

Also, I think it will depend on the quality and style of the interior finish as well.

Seeing my wealth increase hundreds of thousands of dollars due to appreciation in interior locations has shown me that.Everything outside of California and the east coast is not a ghetto Detroit neighborhood with D class tenants and negative appreciation.

The below estimates are based purely on research and have not been quoted – again, I’m looking to see if I’m in the right ballpark.Cost estimates:Electrical/Wiring: $10K ($3/sqft – labor + material)Drywall: $6.5K ($2/sqft – labor + material)Plumbing: $10K ($3/sqft – labor + material)Flooring: $8.7K ($2.79/sqft – just material)Interior Paint: $2K (mostly material, potentially contracting out ceilings and high places)Kitchen: $15K (based on salvaging some of the cabinets, new countertops and appliances)Bathrooms: $15K ($5K/bathroom, installing mostly myself except showers/tubs)Holding cost: $7.5K ($2.5K/month interest only payments for 3 months, discussed below)Titling fees: $5K (for seller financing, discussed below)Total Cost: ~$80KHow accurate is this?

I know I was a licensed assessor for a number of years..You really need to get inside to confirm the interior condition and mechanical age before you can offer. 40% seems really low for expenses on a building that age especially with that water bill.
