Yes you can use commission as sourced funds for down payment on a conventional loan.However some lenders have internal overlays that don't allow it.

I agree with the others here that say you need to have some skin in the game, if you are going to live there yourself, get an FHA loan rather than owner financing, you can get a 3.5% down loan, personally I do not love these as they require  PMI which is an additional expense, and you also need  bring additional funds for closing at least for taxes, title, attorney and transfer fees . borrowing from anyone else for the down payment, to include a personal loan from the bank is not a good idea, those again will be higher int. rate.

And my IMPRESSION is that with MTR you are getting 1) traveling professionals (nurses) 2) relocating professionals 3) Insurance company temp housing for claimant remodels. 

Do yourself a favor and find an expert on your particular system -- that might not necessarily mean one of the big name companies.

You can use the Bigger Pockets management finder tool to look up MTR management companies in the area and then I have a few recs I can provide if you are interested.Shoot me a message if you would like to discuss further and I can help you strategize to make sure you make the best decision possible!

But, if a cost-seg study is done on the old property, you can manage Sec. 1245 recapture tax by doing a study on the new property to confirm it has as much or more Sec. 1245 property.You cannot swap a fully depreciated gas station for a raw piece of land and avoid recapture - you must replace all the 1245 and 1250 property.3) OZ - Sure you can defer your capital gains for a few years into an OZ fund, but the magic of OZ investments is the ability to achieve tax-exempt growth after a 10-year holding period.

One risk I could think of is - Even witb a 20 year guaranteed lease, thr company could bankrupt & may put me in a situation to look for a tenant.

I financed this property using down payment funds from 403B and a local commercial bank. 15% down from personal funds. 85% down from community commercial bank. 3yr balloon, 20yr amortization, 7% interest rate.

Most PMC's will add extra fees to help the company make some extra revenue.

Plus the mortgage company probably calls the loan, and if you can't pay it off then you can lose the property.
