It’s a lower quality standard than most new construction homes.

@Cameron Fowler I’m in northern New England.

Noah here, new to Bigger Pockets. 

On one hand you could sell the property and use the funds from the sale to go and look for a new investment property as you move into your spot downtown.On the other hand, by holding the property you are building equity and the property itself has likely increased in value over time and will continue to.

The zoning will define the permitted uses (this will tell you if you can have an RV/Boat storage there) and it will define the density (this will tell you how many tiny homes you can add).You'll want to make sure you don't conflict the existing duplex to a new use or mixed use where you might put the existing use out of compliance. 

Does anyone have any actual data on the return on this component (previous appraisals, paired sales analysis, comparison on new construction with/without rooftop decks)? 

Vast amount of education on different markets and always current with new webinars, great investor coaches (free to you!)

This is my second post which means I am brand new.

Sellers would rather continue with a buyer(as long as it's a reasonable buyer) then start with a new one.

I think you are asking if their top markets list is a good place to find new markets to invest in.As an avid AirDNA user I like their data and their tool in general.
