I know that finished basement space isn't supposed to be included when listing the square footage but is it technically illegal?  

I'd just hate to see her caught on a technicality when everything else in the case is strong. 

If you're not technical, you'll want to find someone that is so they can help you set this up.  

Yes, but with a mortgage, even though it is not technically a sale, a lease could trigger a due on sale clause that is written into most mortgages.  

It is technically a separate task, so should be treated as such. 

This means it's personal use property which is basically a horrible tax situation to be in.My suggestion is to charge your son some amount of rent (technically needs to be fair market value) that way you can qualify the entire property as a rental property.

It is technically two plots that are joined together, I am unsure as to the feasibility of separating into two plots but will look further into that possibility, but we would prefer to keep both lots together since we recognize the value of the land. 

Technically a 4-plex is multi-family and you can purchase them as owner occupied with an FHA loan with as little as 3.5% down.

My understanding is that technically this may be against the terms of your mortgage, but as it was explained to me, the mortgage holder likely would never even know, and as long as you make your payments, they wouldn't care even if they did. 

Not sure this is the right venue to ask this, but when I try to follow a Biggerpockets Alert link, I receive a "This site can not be reached" error. It used to work, ut for the past several weeks, nothing. I can acces...
