I have a new build in FL in a construction loan that should appraise high enough that I plan refinance and pulling out equity to use as a down payment on another property.Any great investor friendly banks you'd recommend?

My father in law mentioned he would fund the down payment for the new construction loan, but hinted getting a cut of the cash flow every month.

In my opinion this product really does benefit new developments the most as it provides higher LTV amounts on both the construction product and stabilized asset product.

What is your construction background?

Learn about construction costs.

Unless you are experienced in managing construction projects you most likely end up spending more than it would of cost if you had just used a GC.

I have a construction company based out of Idaho (River valley developments) we specialize in multi family real estate jobs doing anything from siding, roofing, new car ports, landscaping sprinkler work, ect!

If it was a large construction company or group, I would tell them I need to be reimbursed.

Alternatively you could just take the drywall you test fit, throw a little construction adhesive on the back, slide it in behind the trim, and use some "mud framing" to reform the corners, give it a quick sand, paint, and caulk.
