Most people outsource the cleaning to the same company that is in charge if managing the fire suppression systems for the kitchen/building.  

@David Perkins finding the right lender who has an appetite for this.

You should study his ads but also keep in mind that markets are very rapidly saturated which suppresses rental fees dramatically.By the way, I'm noticing a LOT more business travelers booking my urban STR.

Onsite fire suppression (i.e. private fire hydrants) need to be supplied and a private fire service maintained.

It is the quickest and straight way to see what investors appetite for risk and reward in a given area is.

I don't know that you would want a water based fire suppression system in a kitchen.

When you get further into the process you want to start picking up the phone and talking to lenders and local banks to get an idea of their risk appetite.

There is a LOT available to buy in Westend, if you have the appetite for it. 

I tried them first, but it wasn't optimal and my banker never actually got back to me on if they had an appetite for it....We have a small Fix and Flip Line with them that we use, but with current rates, they're way more conservative and only funding 75% of purchase and 75% of rehab and their rates are in the 9s which is not too far off from what I'm getting with Kiavi on my Fix and Flip with a lot more red tape than Kiavi.  

That said, co-op investing may be the best option depending on your current living expenses in NYC, risk appetite, preference for location, etc.Co-ops are typically priced lower than Condos and certainly priced below neighboring SFRs.
