The Gulf Shore market has appreciated significantly (many markets have including my primary market). 

If something goes wrong and you lose that investment, you may be so over-leveraged that it impacts your primary home.I never recommend borrowing money (from equity, friends, or relatives) to borrow money through a mortgage.

I am under contract for my my first property, which would also be my primary residence, and was pre-qualified/approved through lender A which is on the contract.

I guess what I'm getting at is it seems like our options are either bite the bullet in our next primary residence where we are currently located, understanding the future opportunity to rent for cash flow looks pretty bleak, or look in other states where we would have more buying power and try to find a duplex or sfh that will cash flow off the bat. 

My primary concern is taking care of the seller whom I bought from, and the end buyer being able to have conventional financing in place as the end buyer.

One of the most common things I am hearing of recent in the community is: Should I sell, rent, or refinance my primary residence? 

My direction is a personal choice - free and clear.If you are in a position to start saving for your first primary in a year.

First, I have about 250k in equity from my primary residence.

I invest in Tampa area and have a LTR  and about to buy a house in next 3 months as primary and then after a year convert to STRAnyone here have a connection who will do  short term JV ?

Full disclosure, I am a Bank on Yourself Professional and would be happy to tell you more about it and determine if it is right for your situation.Hey Stephanie, Although rare there are HELOCs available for Non Owner Occupied investment properties(NOO), we write them all the time at Lower.com.2 points of consideration (1) Usually the Loan To Value you can borrow is slightly lower on a NOO. (2) If you do take it out on a primary you want to make sure you intend to own and occupy for 12 months
