I'd also suggest finding your own rehab estimates as well after walking through.

I'm curious what your original rehab and ARV estimates were.

One of the properties I'm getting appraised .I have A general contractor that already drew up a estimate of 160,000$ .to fix up an repair.

#13 is a buy/fix/rent project near 140th & 11th in Grandview south of Main St.  3/1/0  Bought for $35,000 cash deal the rehab estimate is $8500.  

However, if you will let me come out and inspect the property, I can get you an estimate which reflects the true value of the house."

The estimate was $4,200. 

Is there a difference between the estimates for repairs (e.g., on a buy and hold before you rent it) contractors usually give to investors vs the estimates/pricing usually provided to your average homeowner wanting to update their house?

Estimated rehab costs $20,000.  

I am trying to avoid hard money as the project is estimated to take up to a year due to weather conditions, area restrictions etc.
