Originally, you had a loan of $355,000 with a current balance of $310,000 at a fixed 3.5% APR over 30 years.

What happens if one of you decides to buy a personal home and need the credit to qualify for a new loan so needs to sell this one to make it happen, but the other partner not ready to sell yet, or doesn't want the capital gains. 

I have a fully paid off property in an LLC (open to quickclaim deed for the loan)  that I am trying to use the equity to BRRRR and begin investing.

I am planning to get my first investment house; I don't want to use my savings, so I have an equity line of credit for 50K and got pre-approved for a loan up to 300 k? 

What are some companies that buy these loans?

Thanks, I don't need a loan.

Would be looking for between $600-700k on a new loan to pay off our current line and have free cash to continue to scale. 

That's a high risk loan, and they will charge you for that risk -- something in the 8-9% range currently.

Two major factors: the fact that it's so small and the associated loan amount. 

For a new lease, I will need to create a state-specific one through some online entity.
