Another option can be prepaid rent.

Maybe count that as 20 years of prepaid rent?

I had a prepaid 5 year lease that was not breakable ..

Here's what Fannie's selling guide says:The new loan amount can be no more than the actual documented amount of the borrower's initial investment in purchasing the property plus the financing of closing costs, prepaid fees, and points on the new mortgage loan (subject to the maximum LTV, CLTV, and HCLTV ratios for the cash-out transaction based on the current appraised value).I'm sure you're looking for the best rate, that's assumed.

Insurance is always prepaid before closing or included in closing because the escrow collection is for next year's premiums. 

Mail, in a sealed envelope with postage fully prepaid, addressed to the tenant(s) at his/her place of residence on the same date, as per RCW 59.12.040.[ ] On _______, 20_____, after attempting service in both manners indicated above, I posted the notice(s) in a conspicuous place at the tenant's residence, AND I deposited a true copy in the U.S.

Yes, a seller concession is really only supposed to go towards closing costs, not prepaids, etc. 

I know this post is a year old but I was searching for topics related to prepaid rent because I'm considering it in Texas as well.

if so - best thing to do is to ask  seller to provide a  credit / aka  concession  that you can use to pay costs / fees/ prepaids
