I looked at some of the listing available and the prices are certainly what I'm looking for but according to BP rent estimator the rents are also really low.

I know the book of estimating rehab cost is a good one, but is there any other ways to figure out how a rehab will cost?

That assumption is based purely off of Zillow's estimate so who really knows, but in any case,- Would it be wise to go ahead and obtain a HELOC on the property even if I don't plan on using it for awhile?

It is very strange that they don't even have an announcement on an estimate date. 

I mostly base my estimate on Rentometer to do a quick screen.

I would estimate the sale price in today's market would be circa $85,000.

My bad, I meant the property management fee of 15%.My estimation.

Do you know how to estimate the repair costs of this home? 

Foundation repair companies usually give a free estimate. 

I’m planning to get an estimate and send it to the tenants to fix this.
