In Northern VA I think new construction townhomes are a great option with 3-5 bedrooms.

Because there is deal literally EVERYWHERE, all that changes is how they are constructed and how you find em, that's it.

I am currently finishing up a new construction single family home on a paid of residential lot.

As a GC I can advise try to retain control of your finishing material orders (anything where you need to make a choice ((tile, flooring, lites, faucets, tubs)) vs. construction materials (2x4s, mortar, shingles)) because we get those discounts on the finishing items and we keep them!

Can you receive a loan for a single family home and a loan for the construction of an ADU at the same time?

You wouldn't have to deal with any construction holdbacks / reimbursements which is nice.

We've been doing it this way in the construction industry for decades.Best way for you to know what's it gonna cost for your projects is get estimates/proposals from licensed contractors.
