As an investor, there is a lot of potential for growth, and as I see philly development sky-rocket, I firmly believe holds will generate a good profit in the long run! 

The options are A) treat the contribution as a loan, with 8% interest, or B) Profit sharing of a certain percent, or C) We partner up with weighted shares... like 20/80 with the understanding that he will provide ongoing maintenance. 

You should work along with your goals and stick with pursuing that. 

Newbie here...so I'm tracking, does that mean he'll have to pay taxes on the 100K he profited? 

According to RealtyTrac and the National Association of Realtors, the average Fix & Flip takes 6 months, has a gross profit of $67,000 (before rehab costs are subtracted) and has a Net Profit of $15,000 after all expenses are accounted for.

and when the property is sold, regardless on 1031 status, all profits are taxed that year with no credit since no US taxes were paid.

Are profits from wholesaling treated as short term capital gains then?

Plus some of these rentals have seasoned long enough that even with all of the deductions they are starting to show significant profits from rents alone.

Flipping in the uk has low transaction costs and therefore makes lots of sense, but this post (below) made me a little crazy because in the US, transaction costs make sure the entrepreneur with all the risk/work gets only half the profit....even if it goes well....whereas the realtor(s) and money guy gets half ( or more) of the flip for close to zero risk.

Yep I was going to say if you're doing southern vt, it's going to be most profitable to do air bnb on ski properties.
