i definately consider my ppor's investments. we started with reno'ing dumps, taking the tax free profit, moving into another dump, reno'ing, taking the tax free profits etc etc ... until now we completely own a large, comfortable house with ingound heated pool and 26ft boat, two cars and no debt. bought in 2001 for $400k, recently valued at $700k.
we could've stop there i guess and lived from paycheck to paycheck, but instead we got a loc for deposits on ips. some of the ips we develop and sell off to pay down the loc, but it is always on tap for when we see a "deal". thanks to the house we now have 10 ips and now looking for some land for a small development - all before 40.
none of this would have been possible without our orginal ppor reno'ing plan and subsequently having our ppor mortgage free.
but - the best investment of all with our ppor is freedom. freedom to do what we want, when we want and how we want in my own home. bliss.
