This is where I believe I contribute to the team. 

I'll have more to contribute to the site after doing a few more deals. 

I look forward to learning and contributing wherever I can.

Who is contributing?

According to Chapter Five, An outright gift of the cash investment is acceptable if the donor is -the borrower's relative-the borrower's employer or labor uniona close friend with a clearly defined and documented interest in the borrowera charitable organizationa governmental agency or public entity that has a program providing home ownership assistance to low- and moderate-income families, or first-time homebuyers.The FHA doesn't just list who may give such a gift--it also has rules discussing who MAY NOT provide gift funds for an FHA loan down payment.

Would you rather:--contribute the land to a partnership deal where you end up owning 2 units (20%)?

So if that industry is slowing down I'd think that could contribute to local markets slowing down. 

Regarding your IRR calculation, what was the total acquisition cost and were extra funds contributed over the 5 years period?

In general you would need to know the contributing value of each property feature, and add/remove those values from each comp to get to an actual $/sqft for each comp.  

Looking forward to having you contribute to the forums.
