@Adam Schneider is right, we can't possibly advise you without seeing the numbers...My gut reaction is keep it and pull the equity out to use on future investments, but that's because personally I rarely sell any of my rentals.

Whoever pull your credit ask them what you can do to get higher credit score.

Our best work is usually done by hiring individual handymen and subcontractors to pull specific permits as needed.

If you can rely on the personal loan for unexpected expenses and have credit cards available, I think the extra $1000 / month you have as padding would make me pull the trigger if I were in your situation. 

I've talked my clients out of deals because I knew they would be making a mistake and I've convinced my clients to pull the trigger on deals they dismissed because they didn't have the vision to see how it could be a great deal for them.

The the boiler is natural gas so I am looking for estimates on how much it would cost to install new gas lines, a new boiler, and then a second breaker box etc for the electric to separate the utilities amongst the apartments.

Not necessarily actually pulling the trigger on this particular property!

This BP analyzer is pretty superficial...If you are wondering if you should pull the trigger, you'd need to have a set investment criteria, and then we'd have to ask if the deal in question meets those criteria...this is a residential property valued by comparable sales...CAP is irrelevant entirely...Cash-on-cash merely puts your property on the same level playing field as other similar properties for the first year...it doesn't truly dictate a good deal.

You'd have a hard time getting a loan or you'd tie up a lot of cash that you can't pull out anytime soon.

The tax deferred nature of appreciation and the long term low-risk history of holding New York property make buy-and-hold at cash flow neutral, or even negative, compelling for investors with other primary sources of taxable income.
