He has developed multiple homes in Westchester.

In the midwest, I am averaging around 400 a square for the shingles to be replaced and in California, I am around 425 a square.To determine a square take the width X length of the house then multiple by two then divide by 100.

It was THREE weeks and multiple service calls before it was fixed properly.  

But she is right - it's not in your lease agreement and you absolutely don't have to do it.From your perspective, I wouldn't have any problem doing what you're doing either.

Do you have multiple rentals that you run through your checkbook IRA? 

Just be aware that it took a while and I had to call them multiple times to get it sorted out.

I understand wanting to have multiple sources of potential leads.

The price seems to be about $200k less than anything you could find in San Diego county.I agree with the other comments that you should always go with the worst-case scenario in analyzing the deal (plus the contractor is a better expert for repair costs than your agent, but I would get multiple bids).It doesn't seem like there is enough meat on the bones for this deal. 

Really helpful points and perspectives. 

If the area is stable or growing in population with multiple strong employers, then I'd be comfortable investing in the market at the right prices.
