i actually only invested an additional $23,000 i answered the question wrong

In addition to brokers, I would also suggest speaking to 1-2 regional banks/credit unions.

The standard rate is 3% of a loan, a good broker will never exceed their origination costs of more than 3%.Additionally, a competent broker goes beyond merely securing financing.

Additionally-Sleep a few nights in it.

It added far less value than the cost of the addition.  

There are cheaper one’s in D/F areas but I would be careful as those can create a laundry list of additional issues.

Two days ago it was an investor who created an additional LLC independent of the deed holder entity believing tenants could only sue the LLC where a contractual relationship existed. 

It's a whole other thread to get into but do some research on the issues with commercial real estate, Ben Mallah is a recent high-profile additional person to come out publicly on this and who is putting his $ where his mouth is. 

You should also make sure that you do additional research on STR comps so that you have an understanding of their values as well.

Additionally, I am financially prepared to sustain hard money loan payments for up to two years, which is realistic for resolving occupancy issues in NYC.
