What are some of the transactional funding companies you would recommend using?

My mother, Grandma's daughter is friendly to any transaction necessary that might require her. 

If you cut ties with one principal broker, you are unlicensed until you sign on with another.If your main goal is access to the MLS to work your own deals, you can find companies that just charge a transaction fee instead of take percentage of your commission.

transactional funding...not transitional

I am only looking to facilitate the transaction, bringing the tenant buyer and landlord seller together.In my state a lessor can only collect at most first, last and a security not to exceed first months rent. 

I just sold my TH in Ballenger Crossing this past summer to move into SFH, so I know most of Ballenger Creek doesn't have good rent/price ratios, but it seems that little area of Cimarron/Conestoga/etc might be decent... not sure if you're familiar with it and whether you think it could benefit especially as they develop further south along Rt 85.  

We found a few companies here in Texas & their fees range from $850-950 per transaction.

The title company doesn't accept cash (except for very small transactions), and I didn't have $60,000 just laying around, anyway.

It will help you grow much faster and will be more sustainable because you're focusing on relationships vs. transactions.
