I am a Broker in Austin who flips houses all over the state and while most of the time I just join the local board, I have used pre-paid mls services for as low as $99.

You'll also have closing costs and 14-15 months prepaid insurance and taxes.

Closing costs and pre paids are the other factors getting me to the 10k I am thinking I am needing, what are options for negotiating seller to pay closing costs?

both houses are in Round Rock, TX using 5% down conventional loans with PMI prepaid.

It is always safest to have an attorney review the forms to make sure they are appropriate for your purposes (this service is inexpensive if you subscribe to a pre paid legal service--I can give you a link to one if you send me a PM and ask for it).

Credits back to you would be prorated taxes and insurance, as these are prepaid here.  

Which is like pre paid legal. 

The guideline states "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).The delayed financing guideline states the the new loan amount cannot exceed the borrowers initial investment. 

Sounds like pre-paid legal advice.

Recording fees, title insurance, insurance prepaids, tax prepaids, tax prorations, and the plethora of fees from every government entity with their fingers in the pie still apply.
