So, if you are using this property exclusively to rent out...then it won't officially be a "Second Home" and it would be an investment property. 

If you go to their official website, they have some nice PDFs that describe various scenarios of how you can use VA loans - give it a read. 

@Chris BrallI’ve been a building and zoning official for many years.  

Even if the state law says one thing, often the local officials implement their own rules it seems.Generally in Texas the previous owner needs to request the overage within 30 days.

I have no official numbers but it might be commom actually for high networth types to own in Cali.

Start by reaching out directly to owners who might sell but haven't officially listed their homes.

It doesn't have to be an official form.

There are no official statistics so again, any statistic you read or hear about either somebody guessing, repeating what they've heard or read from another source or lying.However, in this case, you can compute your own statistics using Airdna and that's the only source I would trust.
