By estimating the gross rents, vacancy, and expenses, based on the attributes of a property, one arrives at an NOI estimate.  

I actually first looked into real estate investing back before the crash in the late 2000s and wish I had a resource like this back then.  

Joe Mama So joe, I'm assuming you bought properties close to thier peak market value before the market crash...

It literally lost half of its value after the crash. 

If the figure arrived at is say, 10% "Capitalization Rate", which you might have set as your initial benchmark, THEN you would hone in on the SPECIFIC (Non-Pro-Forma) details about the property to see if that Cap Rate is justified by the current financials and building condition, and whether it's still a "deal" when LOAN repayments are added to the expenses side(?)

If checks arrive late I send them back and tell them they owe the late fee.

I don't have any special insight, but I don't see much risk of a housing price crash or even a substantial correction in the near future.

@Jeff Brower We would love to get some help finding something, although we don't arrive for four months.

Unless you were here in the crash, none of the cashflow numbers make sense, and buying for an appreciation play is a crapshoot - if you're going to gamble, roulette is a lot more fun.

As soon as I got the Corporation in the mail,, everyone backed out; and the entire project crashed.
