No It needs to be your primary residence single family home in order to leaglly pull a permit as a homeowner in nj. if you dont know the uniform construction code, international residential code, dont have a background in construction and dont know the rules and regulations for this state the inspectors will eat you alive on a major project.

Reduce overhead: stop eating out, move somewhere cheaper, drive a terrible car, cut cable, sell your TV, etcMake more money: get a job promotion, work overtime, flip homes, deliver pizza, etcDetermine what is your highest dollar producing activity and do it as much as possible.

Also looks like you will have maintenance/capex costs which will eat your 6000.But, if this is an area where rents are rising and values in general are holding or increasing then it could be a very nice long term hold that supports itself.

Do you eat food?

If you are not familiar, it is one of these gig style jobs when you deliver food from local restaurants right to the customers doorstep, similar to Grubhub or Uber Eats.

But a little table one could also use for eating would be nicer.Most business people will want to chill after work, not socialize with the strangers.

That's not a good place for any fiduciary to be.My bet is that niece Nancy and her lawyers are going to eat your lunch.

So that may potentially eat your cash flow.

But you could bunch the sale of a few of your rentals and use the proceeds as one down payment on a good NNN with a 15-20 year lease.Either way I vote with everyone else - a dog now isn't going to stop eating food. 

As said above Network and pile up cash, plus live simple, eat simple and get this behind you as quickly as possible.
