That monthly surplus almost makes it a no-brainer to go for MTR.

I rent to one couple or small family for the full rental period - no less than 2 months and no more than 3 months.

All things considered, on the market for months, its now winter time, cold weather, holidays, and dark at 5 pm, not prime selling time, I offered $250,000. 

"A second question is if I finance the car purchase can I also deduct the business use portion of the interest charged on the loan?"

And, if feasible, charge for parking!

We negotiated it down from their original asking price of $1.8M but it needed to be a cash deal because the building was 50% occupied and of what WAS occupied was month to month office tenants.

My first goal is to hit 5k per month in pure cash flow and second goal is to hit 10k per month in pure cash flow.

One month of vacancy has cost you $2,400.

My suggestion would be to cap your utilities at a certain amount and have Tenants pay anything over that amount.That will help you manage your expenses, and also allow Tenants to gage their usage each month, and make adjustments if they don't want to go over the allotted amount.As far as collection, provide the bill showing any overages and just have them pay for it along with their rent. 

A $1700-2000/month rent doesn't get you cash-flow on a fully leverages (after refi) $240k property. 3.
