I am absolutely enthralled with the podcasts that were produced by Bigger Pockets, they are awesome!

Last option is to just move on to the next deal if you cannot produce a valid POF

I would like to acquire more properties to produce cash flow for retirement.

And I tried to be as comprehensive in my modeling as possible, including purchase and sale closing costs, the value of tax deductions, management costs, etc.I know this community is dedicated to investing in real estate specifically, but it's still an investment, and every investment is measured by the profit it can produce and must compete with other options.What am I not understanding or missing here?

Cash flow is the difference between the rental income of an investment property and its expenses... it’s not all the income a property produces.   

@Xela Batchelder  There are a lot of different FICO score versions in use, and each one can produce a different score. 

It has an apartment that is rented out in the back and an attic that is plumbed for an apartment addition, so there is an income producing aspect to it even if I purchased it as a primary residence.My question is can I purchase the property with a partnership LLC (which already exists and owns property) and then rent the main house from the LLC for myself to live in?

If you can put down $35K each on two new purchases of $140K and pay a total of $5K in closing costs, you have $70K equity, but maybe a higher ROI than the one condo produced; maybe not though.

Sounds like an unlikely case; if they can’t produce proof of payment to help you get them their money back then doubtful they can provide it in court.

In this same vein, if you look at the $150k or so that you would net from this sale and evaluate what you would do with it, hold it responsible for producing results that BEAT holding it.
