BLINKERS OFF GUYS  It sounds like your earnings are gambling earnings so I would strongly recommend opening up an llc or Corp and pay yourself a k-1 income.  

that's for him to gamble on.

If you do not have those and still buy, you are gambling ... you may win, you may lose, but keep doing it and eventually the odds will catch up to you.

I'm just waiting on getting back home from offshore to get the house rehabbed.

Also that gap in title records is a huge gamble, which is why the title insurance company won't touch it.

Not sure, because at that point you're speculating appreciation, which is more of a gamble than investment.Refinancing to break even and using the cash to by a cash flow property may make sense.

Also, how would I even go about with the financing and getting investors to sell the whole thing to after everything is completed and under construction, especially offshore investors? 

Maybe if you thought it was going to go up to 450k it would be a good deal but that is essentially gambling.

If your history shows that you haven't used it correctly in the past, why should they take a gamble on you now?

@Wilson Tang I would need a bunch of research if I am going to gamble 100k, it is good to equip yourself vs believe what others say.
