I am not trying to be rude, I am just trying to point out how ambiguous your question is.J Scott gave you a massively wide range for the same reason.When it comes to rehab, there are way too many components to rely on a square foot budget.

Well, the big challenges (rent control/stabilization, tenant friendly housing courts, tough renovations/need for expeditors, etc.) is NYC-wide, no differences between the boroughs there.As for Manhattan proper, my take is it comes down to two distinct reasons. 

The MHP is almost 40 years old and made up of mostly single wide trailers.

I currently own a double wide and recently sold a modular home.

You can read the details and submit comments to HUD here:  https://www.federalregister.go...Given that vaccines, jobs, and housing assistance is widely available, I question the need for such a ruling.  

When I got back my kitchen door was wide open, he was on a step ladder, goofing with the wrong fixture.

As for possible cash flow, I have looked around our area and the rentals cover a wide range of prices, so I'm unsure how much we might be able to pocket.

The experience is amazingly wide ranging. 

I have a wide array of knowledge, but need some direct real estate experience, and someone to help me put it all together.

will allow me to pay a small 3.5% downpayment.I'll continue posting my journey here on BP as I continue reading and learning from you & the wide variety of other experienced REI's.Thanks Brenden!
