One person might want to fix and flip it, and the other person might want to keep it.

The goal would be to capture that interest rate and keep it for the next 25 years so that I can cash flow well, if I move again and rent it out.

this  make sense  if you were planning to  refnance  the  1st mtg anyways  ...otherwise  - I would either keep looking for another 95% heloc  or  make due with a  90% cltv  heloc program 

keep looking and don't give up. when you say you're trying to 'match' your current monthly expense of $3K, I'm assuming you're saying that you're hoping to pay $3K net against the mortgage after collecting rent - is that correct?

Owners/Operators have to identify new and innovative ways to offset these expenses just to survive.One of the most common solutions I keep hearing is bringing property management in-house (aka vertical integration).

Explained the situation and he said it may be a challenge to get another conventional loan (investment loan is being considered as well but; Family loan = plan A, bank loan = plan B).We want to keep the property we live in now (since Oct 2023) and rent it out when we leave.

And I'm keeping it free for everyone who's interested to read and maybe collaborate on and refine it.
