Under the legal concept of "tacking," the possession of each owner is tacked onto the possession of prior owners for purposes of determining the relevant time period.

You hear a lot about a "50/50 split where one partner provides the cash and the other provides knowledge or sweat equity" really doesn't make sense.The concept is that investors make money off their capital or credit servicability.

You'll want to learn more ways to increase your income now and in the future, keep your expenses low, and take the difference to invest into assets, real estate/business.My favorite concept from the book for someone in your position is the "Runway".

@Andrew Low in addition to what everyone already said, the concept of OPM is more so to use as little of yours as possible.

The crawl space was not really properly constructed in that was build with some basement concepts and come crawl space concepts. e.g. the insulation was in the joists with facing down - yet the mechanicals below that and with the opening to the basement, it is a "semi heated space" - which is good because the water lines are not insulated.

Plus the fact you were able to expand that concept means you must’ve been on to something!

I haven't completed a 1031 in the past and don't really have much concept of cost.
