In concerns to those vacant lots, I wouldn't have any clue how to get that info besides accessing the county assessors office for some tax info about the owner.

Quote from @Stuart Udis: @Robert Ellis In order for the QOZ investor to reap the tax benefits the hold period has to be longer.

You've done a great job with keeping your debt low so I have no concerns about your level of discipline to use/reuse a line of credit.All the best!

Is taxes going to be higher today or higher in the future? 

Once you retire the title and place a mobile home on its own lot then our county taxes as real property and we pay property taxes like a stick built home vs a mobile home in a mobile home park which is taxed like a car - vehicle tag.4. 

Also don’t know your taxes there.  

There is such a shortage that state government is giving tax breaks to developers to build more multiplexes As far as specific towns I'd say Nashua, Concord, Manchester, Durham (where UNH is), Dover (right next to Durham), Portsmouth, Seabrook, Salem, Exeter and Hampton.I chose Dover because its a mix of students from UNH and young professionals. 

How are you structuring debt vs equity?

One time when I bought on owner financing, I totally forgot that I didn't have property taxes included in my interest-only payments to the seller.
