The few lenders I've reached out to in my area (local banks, credit unions, etc.) are only working with primary residence for Helocs or Cash Out refi.

I have been working with a credit union to get a HELOC to allow me to tap my equity to buy additional real estate.

The other option I would consider is regional credit unions that hold onto mortgages/loans and don't sell them to the secondary market - they are "portfolio lenders" and have the ability to be more flexible with their terms.

Is there a bank or credit union that offer a loan for it?

You could look into a cash-out refinance with a private lender or a local credit union.

before you go searching for higher priced HML.. check with a local credit union or COMMUNITY bank..

there are national lenders everyone's heard of (Chase, BoA, etc.) and local lenders (regional, local, credit unions, etc.)call a bunch of both. 

Even if zelle is available through a bank or credit union does not mean they will offer it for business accounts. 

If you plan to stay in this home for another year, you can do up to 100% Heloc with several credit unions.

@Tanner Johnson Go and talk to the local credit unions and banks in the town or the neighboring town.
