How much rehab are you looking for? 

Plus, it integrates seamlessly with accounting tools like QuickBooks, making bookkeeping much more straightforward.Whichever account you choose, look for one with no monthly fees, online banking, and features like automatic bill pay.

Or maybe one that's move in ready, whereas most of the others need work.

We have an existing mortgage (backed by these 2 lots and 2 others) and given the increase in appraised value there is no need to pay anything back to the lender when selling the lot.

If they understand they need to leave and discuss honestly what they can do to make that happen then you are both working to the same end.

It is much easier to find HELOCS for your primary residence, but some lenders will do a HELOC on a investment property as well 

Extensively commented on, no need for me to add to it.Warehouses is somewhere towards the bottom.

Too much effort and too much risk for the OP.  

I'm curious, how much rehab work did you have to do on this property? 

Most are very much on the market and subject to bidding.
