But I bet you got the benefit of starting with it being your primary.

For anything that benefits both units (yard work, maintenance, etc.), I've been tracking the mileage and I'm assuming that I can deduct half of it on the first unit since the other half is for the unit I'm living in that hasn't been placed in service yet.

There is also a cost benefit to writing off some of the expenses you should discuss with your accountant or tax attorney.

I have been through 4 banks, 2 credit unions, and 2 mortgage brokers now and none of them will allow the seller to carry. 

It just seems uncanny that the credit union has better rates and better terms.

My credit is good. 

I got a conventional loan with 5% down, 30yr and took a 4.25% vs a 3.75% to receive about 2500 back in lender credits on my down payment. 

Please share what the 'tax benefits' of an LLC are.  

Which will create a maximum down payment of 18k(20%) plus other expenses.I have about 20k available in LOC and Credit cards.

Looking to interact with other investors to mutual benefit of course to start it will be one side for the most part.
