also what is your targeted per unit return?

While I have owned homes before, I have never house hacked so am looking into resources here on BP as well to learn more.

BiggerPockets is full of resources designed to help you along your journey, whether you are just getting started or a seasoned investor.

They should not have been this off and you should always use the worst-case scenario as your target number when you are doing a flip or BRRRR.If I were you and a sale wouldn't net enough, I would do mid-term rental there instead of long-term rental so you can earn more, but still not have a ton of tenancies.

Besides Ben Mallah, what are some other resources that I can familiarize myself with to understand the current valuation and the trends? 

Blake is awesome, priceless resource in the PadSplit world.

The towns you're targeting—Rochester, Dover, Farmington, and Milton—offer great potential, especially for flipping and buy-and-hold multifamily investments.

Any insight on neighborhoods to target for LTR, or lakes to target for STR (open to non lakes as well).  

You can also just check active listings on Craigslist or Zillow and see how much properties/units are renting for in your target area.

It's also worth mentioning that I already have a good relationship with a wholesaler in town who knows other good contacts, and I am able to use some of these contacts as good resources for general knowledge and learning how it all works.I recently had to close my business of 9 years, and so instead of getting a W2 job or start some other "normal" business, I'd much rather prefer to have house flipping be my primary source of income.
