When you do that, it can become a write-off.Of course, I'm neither an attorney or an accountant, so take this all as my opinion formed from personal experience. 

Don’t write them off.

They have both NJ and NY offices and they write nationally. 

I would suggest myself to listen to the BP Podcast (all episodes) with a notebook next to me and write not only EVERY RE book but also every business related book suggested!

To get around this without having to pay off the remaining balance of the mortgage (Due on Sale Clause), our lawyer recommended writing up a side agreement between us and our LLC stating that the LLC has the right to use the property and the first right to buy the property once the mortgage has been paid off. 

First I'd be remiss if I didn't thank the BP community especially those who take the time out of their busy schedule to write posts that would come to be immensely beneficial to new investors like me.

I trust that Brandon would write good stuff.

I was told by a broker to submit a resume along with my offer for seller financing. This is the first time doing seller financing and am wondering what should be included in such resume?

Assuming you were upfront with the seller about wanting to sell the houses, try to write an amendment into your deal to set release prices on each home.

My advice would be to write an offer with the fewest possible contingencies - and if you were in Maine, I'd go $5K over asking.
