Homes are selling on my street from $460-$525k that are the same size/layout.

I bet they have a list of approved education/licensing criteria service companies you can choose from. 

Just be sure the window sill is less than 44” from the interior finish floor and the window and egress sizes are per code to be considered an egress well.

I am looking for a SFH or condo that is 2/1 to 3/2 in size.

What size commercial multifamily are you looking at and what is your price point? 

That said it was twice the size. 

Be careful as you are navigating different neighborhoods, some of them have specific overlays when it comes to population density that alters the lot size requirments, often at the detriment of the investors.

All GE appliances with full size stack able washer and dryer.

It seems that you're right in an RV not being an ideal fit for your family's size, so I too would scrap that thought.

Remember RE is a long term play so if you take minimal losses short term to get exponential return long term then that's a good bet.
