Correct, I use real estate agents for rough numbers as they are less expensive, obviously not as accurate but good enough for his purposes..

My investor friend who is quite successful told me that was not a good enough... that I needed to find comps knowing exactly the upgrades in each.

Just knowing the neighborhood or area is not good enough.

You offer the 90k, because if you get it for 130 and that's not a good enough deal at 130, you loose.I've bid higher (and gotten) two different properties over the years, and I haven't regretted either one, so that's not the point... the point is whether or not it is a good deal, and we'd have to know what the ARV would be, and what other options there are in your market before we could advise you to chase it or not.  

Around here, that's a good deal, however, not good enough for me to chase except that with this particular deal the seller is helping with financing.I'm not looking forward to managing it, but I need the cash flow right now and it will bring me that.  

If you have a good enough deal and have some funds, you said limited so not sure if thats zero for this or some, then usually a good deal will get funded somehow.

If i had no other way to do the deal i would probably go ahead with the 50/50 if the deal is good enough.

They worry about what kind of scuzzy messes got spilled on them from the previous tenant, did the carpet cleaner do a "good enough" job?

They might not be getting your business on this, but you never know in the future.I think foundation issues are worth buying, if you know what you are doing and get a good enough price for the risk.

So, it seems real estate licence seems good enough to do estimate.
