Recently a duplex came on the market that I am really interested in, it is located in an A neighborhood.

As others said out of state can be more challenging based on location but local or out of state both can be done. 

CT is 1-2 hour drive from my location depending on the town and is manageable for one project.

It is located in an area that attracts college students/employees, working class families, and military families.

I am a realtor, investor and own a construction company located in College Station, Texas (home of Texas A&M.) 

Great location on main hwy. 

I recently came across 1 acre asking for 314k in a very good residential and growing location, so the current owner has added 4 manufactured homes with 4 electrical meters, 4 septic tanks and only 1 water meter for all 4 homes, the homes are sitting on partial slab and partial pier & beam, he also added 2 storage sheds approx. 380sqft with the intention to make them ADUs they are still only the shell so I would have to get those ready to live in, so currently the 4 manufactured homes are being rented and bringing in 2800k a month, 3 of the homes are needing some TLC which could increment rents and possibly get me at 3600k a month, also being a 1ac lot this still leaves about 12,000sqft of raw land where you could build etc.So that is on the good side now the things I did not like so much, the lay out is poorly executed to where it makes it looked crammed up and not professional but it could be fixed.Another is that in reality there is only 4 livable units so that qualifies under a conventional loan but since they're are 6 units on the property the banks are wanting to take it as a commercial so we would have to move out the 2 storage sheds out in order to close as conventional.Another concern, technically you are only allowed to have one manufactured house or single wide in your property according to what I know but I know it could change according to zoning which I will investigate, so my question is has all this been accounted for and if so how can I verify it so it wont leave me in a bind further down the road, I currently asked my agent for the appraisal of the property to see if that might verify.Any recommendations?

So buying the right location will become increasingly important here to protect you in the long-termFood for thought.

I will not know that until I climb under the house and into the attic etc... for inspectionThe area is close to things and is not in a indicated crime location and has a very nice open lot area on the corner with it but again assuming the tenants stay and lease I am looking at that as a smaller issue..Thanks for bringing up the concerns but I have tried to do my due diligence but do not really know is the analyzing aspect has missed something major.

Make sure you know the rules in the state where the property is located.
