Sounds like you put in a ton of work to maximize the value, and that basement addition was a smart move.I noticed you mentioned the NYC luxury tax and some of the rental pricing challenges—have you considered expanding your portfolio in markets where you don’t have to deal with those kinds of headaches?

New Britain is where you are going to get the best ROI like you mentioned and this is because as a whole there are more areas within the city where qualified tenants are looking to live and the purchase prices are lower while still maintaining competitive rents.

Now that we are 10 days from closing, I am talking to loan officer to get the Closing Disclosure so that I can know the exact cash to close (I need to move money from brokerage to bank account) and he is mentioning about 2% IPC limit. 

If you get your system and modeling down and follow what I mentioned above with respect to coming up with your strike price/offer price, you shouldn't look back if someone overpays for the property.

That's why I came across turnkey properties for some hand holding as you mentioned.  

Not only is the FedEx super hub close by(as @Aristotle Kumpis mentioned), but airports in general are usually near commerce drivers, meaning they work well for finding good tenants.

The success of such investments depends heavily on local market conditions, and maintenance and upkeep costs can add up, especially as the property ages.

The problems you mention are just known issues.

I own units with no kitchen window and have had tenants mention that it just feels weird. 2.

i have looked into the Landlord locks as mentioned but have not used them. i have one student rental where i use an electronic lock ( that i can control from anywhere, change codes etc.), but the bedrooms are regular keys, as @Jonathan C. mentioned for the front door, the unit is set up to send me an email when the batteries are low. i also have another student rental ( 8 rooms, 2 entry, 2 units + utility room) one master key and each bedroom has its own key that will get students in the entry, there unit, and there own bedroom. had a locksmith do that one. cost me a few hundred dollars with keying and supplying the locks ( 13 total ). i like both setups but may look into the landlord locks again for my 3rd student rental i just purchased.
