On top of that there is a plethora of ways to invest in real estate and there are probably hundreds of different ways to analyze property investments and project outcomes.

Hundreds of L/O deals are done every day.

Large franchisee with a track record and hundreds of stores.4.

I am seeing some as low as a few hundred dollars underwater all the way up to nearly $50,000 underwater. 

I can't imagine this running into the hundreds of thousands of dollars, correct?

Typically these companies manage hundreds if not thousands of properties.  

We won the bid at 63,500 the bank was asking 70,000 for it  I got three different contractors to look at it and they said they could rehab it for eighty five hundred dollars one contractor said 9500.00 .

Once in a while I have to pay to repair something, but I've already made several hundred dollars, plenty to pay for the repairs.It's kind of like insurance, but I don't pay an insurance company.

I am a new investor sending out yellow letters and have gotten a few positive responses from the first hundred or so, with one possible deal (so Im on track I think/hope). 

A week before closing I get the email from my partner that was sent to him from the lending company that because the appraisal came back lower than expected, now we have to come to the table with forty five hundred more dollars. where as before they said we only needed 2,000. to close. the realtor showed the comps coming in at 135 to 140.000. so we didn't have the extra cash so we lost our earnest deposit and money wasted on the appraisal.
