When transferring real estate as a gift, it does not receive a step-up basis, as it does when it has been inherited.

Quote from @Nick Am: @Michael Plaks--> The SE taxes are STRICTLY NOT in addition. 

Are there any additional considerations?

Hey Tyler we hate to hear that your experience was negative sincerely we would have hoped that we could have come to a resolution we know that you and your partner had made a request that we do $800 of work that was unfortunately not in your scope of work at the time we had exhausted $4900 in additional work to ensure the property was to satisfaction which included a new hood range upgraded lvp flooring additional framing  new window and a paint upgrade from a single color format to a multi color format and can lighting all of which was never in the original scope and unfortunately when we requested that we do the work you declined I’ve attached before and after videos of the home for reference https://www.dropbox.com/scl/fi/h0ddll4cyp5g5gq12o73s/Video-J... always twos sides to these stories.. 

Interest rate on the home is 2.6%, so I don't want to pay down the loan with the additional income coming in.

I was delighted with their service and be happy to do a introduction for you to my contact manager (I am not associated with the company nor do I receive a referral fee).No business cards but line of credit yes.Revolving LOC? 

Additionally, the boots on the ground partner has to be extremely trustworthy.

Additionally, confirm the transfer won’t lead to property reassessment, which could increase taxes.

With substantial equity in your Fort Worth rental, a cash-out refinance could free up funds to purchase additional properties.

I would suggest getting another full-time job for the time being and investing/doing STR on the side until you can fully and comfortably replace the income that you would be receiving from your job.Is your LTR in need of repair?
