@Sylwia Leczycka If you will manage the property yourself, I would go for option B for a few reasons: 1) If you live on the property you can have access to mortgages that require less downpayment (FHA, USDA etc);2) Living in the property should make your life easier as a landlord, since you would not have to drive for hours, at night, during winter (just to make things worst) in order to see a small plumbing issue they are having;3) I also believe that tenants would tend to be more respectful to the rules if the landlord is next door;4) As the saying goes: "the eye of the master fattens the horse", so another plus of living in the property;5) If you have a condo you would have to deal with the HOA which, sometimes, do not make things easier to landlords (I've had some experience on this one).Hope it helps you.Just as curiosity, which areas of NJ are you looking at?

Moscow is cold in winter and has a small river:Source via Wikimedia.orgResidents of Moscow buy houses in Florida for winter holidays and yachting.4) There is an excellent education in the United States.

He used a different inspector every single time.When it comes to remediation I believe that there was nothing done at all (except windows change and that was done to not to loose so much heat in the winter).

I moved my business here two years ago from the warm west coast and have had quite an education in east coast winter property management (burst pipes, boiler blown, wind/snow damage).  

Some people may want to keep their dog in the basement during the winter to prevent it from becoming a Popsicle.Or some may want to let their kids play down there on rainy or snowy days.

We have extreme winters that maintain -30 degrees Celsius for months on end. 

These work great to validate or dispel tenant complaints for cooling and for heating in the winter.

We didn't have AC until October, didn't have heat for the first winter.

I am in the United States Navy and going on a year long deployment in the winter of 2022.

I would say we definitely don't have the most forgiving weather in the North East as the winters can be pretty cold and the summers pretty hot, but if that's not a problem for you then I welcome you to check it out!
