They should do a cash out refinance or a HELOC when rates go down to tap the equity. 

Contractors, unless you have a working relationship with them, normally do not want you bouncing ideas off them.Understand what their hourly rate is, have a discussion with them that you are okay with paying them an hourly rate if they walk the property with you and provide you a scope of work along with an explanation of what you can/can't get away with in regards to improvements.ask them if you go with them, if they can credit you the amount that you paid.Once you develop a working relationship with a few contractors, you can bounce ideas off them and expect quality responses.I do not invest in New York.Best of luck. 

I'm curious what lender would take something that can have swings of 50% on a weekly rate as collateral?

The main reason I decided to sell rather than hold was the rising interest rates.

Mortgage rates and PMLs are 8-12% plus points right now so the deal has to be a low enough entry. 

In this case, since they are borrowing their payments, these would get added to the principal balance each month, and interest would be calculated on that.If, for example, the interest rate on the note were 10%, they would implicitly be borrowing their payments at that rate.

Very much like the formula the instructor gave the class in a COBOL programming exercise when I was in computer school.

Rent rates have increased so quickly over the last few years.

You can then rent at market rate but have to register it with the town annually and abide by their annual inflation rules.

I like the space as this is pretty fragmented vs MH, so cap rates seems to trend higher.
