If mini split thats 1 of those per unit/room It is not a mini split condenser per room.  

@Alberto Fernandez not sure about NJ specifically but my parents live in NH and recently changed their house over to mini splits. 

I need to replace the carpets, add a shower door, and a mini kitchenette.

That would be from $6,500-$8,000.I plan on either having window AC units, or perhaps mini-split systems, I have not decided.I have a tight budget, but is the rewiring something that needs to be done since I am renting it out, or do I have other options.

This could run another 10-40k depending on the solution used (mini splits or HVAC).

New Double pane windows, new roof, siding, new drywall, restored hardwood floors, complete bathroom remodel, new cabinets and granite countertops , a complete electrical upgrade & for the most efficient heating and cooling 3 mini split heat pumps have been added.

No [Should be Yes (I think--Unit 1 has mini-splits; Unit 2 has central air)] # of Fireplaces.        0 Garage Size/Type   None [It has a detached garage.]

I have seen that many times the cash on cash is a better metric, and still able to be met in mini markets.When I talk with investors who are interested in your market near Charlotte North Carolina we talk about different ways to solve for this problem.

Besides closing the door to the house, we added a mini split for temperature control and a entrance from outside for full privacy.
