@Omar Ruiz all these new strategies are interesting and sound fancy but until you close any deals, you can't compare the impact of each strategy.Let's say, a year ago (13 months to be precise) I mailed 30 letters to absentee homeowners.As for now, I've sold 2 houses from that mailing and one is still listed for sale.

A gentleman I've used recently was JR at Precision Renovations.

To be precise I have done 3 Agreement For Sale purchases.

I’m not sure if I will use it on my rentals but I’ll definitely take advantage of this option to decrease my personal housing payments over time, which puts more cash in my pocket each month.One thing my lender told me at the time was that while every Fannie/Freddie loan can take advantage of this, not all lenders or services will support the option, precisely because of the fact that they make more money via refinancing.

Mike Cumbie - Precisely. 

Whether I truly understand the exp "model" or not, this statement is precisely the reason I despise MLM companies.

Modeling tax items is very difficult to do precisely.

To be more precise, ROI, calculated as (gain from investment - cost of investment) / (cost of investment) does not go down with time, unless you generate losses over the years.

Also, I think this could be more precise than my list.

I'd also think it would be difficult to precisely estimate all costs that will be paid at closing (e.g. prorated taxes) so that seller literally walks away with exactly the amount you discuss with them.
