And while it can still be "a deal" at that point, as Warren Buffet says: "It is better to be approximately right than precisely wrong."

If you think you can make the numbers work with a $30000 budget to fix it and you want to put an offer in, I would contact a local foundation repair company to get more precise numbers during inspection phase.

It is precisely after this time when an investment really starts to show you how it is going to perform and a Turnkey company has to earn its' reputation.  

Precise numbers?

Ashish Acharya, Thank you for the very clear and precise answer! 

I would put the neighborhood or nearest major cross street if that's more precise/useful.I would be careful sending out a flyer to buyers, that you don't advertise as if you own the property.

What are you looking for precisely, lawsuit protection?

@Brian FooteHiIt's going to be hard to say precisely without knowledge of your market however those rent numbers are pretty good if I'm seeing the $1600+ for what you're getting into the property for.The 'gotchas' that I see that I'd want you to really be comfortable with would be that repair cost number - this would have to be a pretty light rehab where you're maybe doing a facelift, etc. 

This is precisely the benefit of having a buyer's agent. 

When the homeowner starts falling behind on his mortgage repayments, the bank charge them hefty penalties which over time add up and can erase any equity the owner has in the house.Unless you talk to the owner or the bank who holds the note, I don't think you can precisely know how they owner owes when they are  not current on their mortgage.
