@Sang Nguyen I would recommend speaking with a Mortgage Broker - they do business with my many banks and different lenders and have access to the best mortgage products and rates on the market.

You might find lower rates with other types of loan products, but commercial portfolio mortgages seem to be readily available and a common loan product to use. 

Dan I think PPSF won't work here, as you have two different product types (3-fam & SFH).

Questions 3 and 4, there are new products coming on the market all the time.

I suppose glue-down vinyl plank would not be an option, but I'm not sold on the glue-down products anyway.

I am aware of the matterport, which I would consider a bit more of a luxury than what our product would be (main difference is the 3D rendering feature) and I’ve found a few other VR resources but none seem to have the mobility part down like we do.I guess what I’m asking is: what are the gaps/voids in this technology currently?

I also look forward to seeing the final product.
