Your dilemma is exactly why I took my properties back and developed a software to simplify management so I can do it myself. 

For instance, in NY, back then, if I buy health insurance for myself thru the business, I have to extend that to my employees as well, so I do it thru another business that I'm the sole employee.

All contracts (whether they were made under the new (after Troika) rental regime, or old rental regime), independent from age or health status of the tenant can be cancelled.

Also found same issues not being able to get in contact with them.About a month and a half back I got a letter from the county health department about violations with the property.

Here is my dilemma -  Most of the multifamily listing I see on Zillow/Trulia are older properties in-general which are mostly not Net-Zero houses (The net result is a zero or near zero electricity bill), so I am wondering is it better to build a multifamily property which can be a Net -Zero or purchase and renovate an older property?

However, thanks to ECU and Vidant Health, Greenville is a growing town. 

I would also run the addresses through the enforcement database and ensure that there is no pending demo order or some other insidious board of health issue. 

I wish you and your lovely fiance health, wealth, and happiness!

Dilemma: I don't have a broker's license or Real Estate License.

@Matt Matyas To have an actionable plan that will work in your area, you'll need to speak with the Town/county board of health and/or a reputable septic installer/maintainer.
