It’s always a good idea to consult a local real estate attorney and title company for more accurate estimates in your area.

Quote from @Roger Garner:Multiple estimates and get some photos of their work too.

If it'd be helpful to go through some details feel free to reach out, happy to explain more.

I need details. 

I'm not following you, can you explain in more detail?

This was very hard and time consuming, but I'm on the other side of the permitting process and ready to build.I am estimating the 6 cabins will be about 900k to build and will be worth 2x that when built.

Would be happy to meet up and discuss your goals in more detail.

If any of the specific areas catch your interest and you’d like more details, these are only portions of the full reports I wrote on each submarket and I am happy to send the full report to you, feel free to send me a private messageAfter conducting thorough research on the economic and infrastructure developments in Alexandria, Virginia, I believe it holds strong potential as a long-term buy-and-hold real estate investment over the next 20 years.

We typically estimate standard costs for these items but get them done much cheaper with our own crew.

Couple of things I would add as I am an investor and also a licensed GC(i.e. builder)  there in the area. 1) That property might have a zillow estimate of 1.9 million but its only 4,000 sq ft.
