New construction loan advice would be great also.

Would you host guests while construction was going on? 

Unless you have construction experience you are likely to end up in the red on the first project or two.If you are intent on trying to do rehabs (which isn’t necessarily a bad plan because that is where forced appreciation and higher returns are) then you don’t need to make a decision on BRRR vs flip now, you can wait until the rehab is finished and figure out what makes sense to you.

DR Horton added 700 houses this year and they are the newest to the market. new construction is on fire. 

I literally have our inspectors plug in the device and we're up.The last benefit, which wasn't even intended at the start, is guest email collection. 

I have construction loan loan on the rehab, and we will roll to a VA loan upon completion of rehab.

Ex: Best inspector to get for section 8 inspection.

have you looked at new construction?

I know as a Seller on my new construction I will not sell to anyone using Rocket mortgage and am careful with well fargo.

I would not cancel the deal- I would allow the seller to do his thing, then schedule a final walkthrough  and bring a 3rd party with me (contractor, handyman or inspector).
