You probably have another dozen options stretching from the Cape up to Southern NH too. 

Most of the houses we purchased sight unseen ended with regret and a lot of work, but the one we didn't back out of is cash flowing, so just assess your situation, make the most of it, and move on.  

Or, better yet, just track S&P and bypass the fees.I hate to be bringing this news to you, but the skill of driving screws is a dime a dozen out there.  

if the property is in an HOA be careful about past due HOA dues and assessments; e.g.

That spread was to single family dwellings.Other expenses and amounts to capitalize from improvements are anticipated as well to be assessed with respect to rental income and increased equity.Example and considerations:If I buy a house that has a 7 year roof,  in 8 years it has reached the end of it's economic and physical life, a repair may cost $7000.

Yes, they can be had cheap, but cash flowing them is the challenge:  HOA fees and special assessments are only a few of the costs…let alone the PITI, repairs, vacancies, and less than predictable appreciation.  

I search the property on the State department of assessments and taxation to see if the owner's mailing address is the address of the property.

ON the surface this seems like an OK deal based on the rent vs the price but that is a pretty crude assessment. 

I was wondering how to best gauge the assessment of a two new quadraplexes I plan on building. 

There are many neighborhoods in my area where I don't need to pull comps, I can walk through and assess repairs/improvements and be close enough.
