While we do run a business that is for profit - you always do not need to be a hard ash and if someone is going to work with you, then extend the offer.So this is what we did, and guess what, she did not trash the place, she moved out and took all her stuff and left the home very clean and spotless.

It just needed cleaned up and redesigned.

I’m also curious if it's possible to convert these units into regular apartments, as this property is located in the NY suburbs.

We took over the management and built relationships with the various agencies and have been leasing the units more regularly with 2 vacancies remaining.

Meaning you will not be able to furnish a clean title within the time period.

They also have strict rules for renters about sharing the kitchen, cleaning, etc. with monetary penalties for not complying. 

Also if he is just taking PITI into the equation, he is missing/withholding info about utility costs, stocking/supply costs, cleaning costs, etc. 

You need someone with boots on the ground to drive by the property regularly, inspect every 3-6 months, supervise maintenance, etc.

I have a couple of rental units in Hixson and need reliable lawn care to mow on a regular basis. 

sounds ridiculous but a situation ive encountered multiple times. ask yourself how much extra work you want in your life, offsite landlords get put out of business regularly, I've seen it over and over again. consider your options and learn everything but diving in.
