They removed the majority of items and then left me to finish up.

I had to carry a LTV of 110% (I had a $110k mortgage on a $100k property). 

I have a list of items he has to maintain regularly.  

Since you already own rental property, you can generally expense items like this against your existing property.

They will also deliver any quantity of items right to your job site for $20, doesn't matter if it is three tons of lumber or a single bathroom vanity.

If you are slow in winter, rehab a house hands-on in winter or if you can find a house where the carrying costs are REALLY low, keep a project ready for when bad weather keeps you from working on paying jobs outside and you need an inside job to stay busy. 

Unfortunately, it’s very difficult to obtain, there’s only a 70% recaptured limit (you forgive the last 30%) and many other items that make it unreasonable.

Here's what I found for NY:"It is illegal for storage unit operators to seize your property without providing the following information: an itemized statement of the amount due. the description of the property being seized. the nature of the proposed sale, including the time and place."

That includes items such as a bigger water meter, work in public space, updating the energy efficiency, fire sprinklers, and so on.

If you find yourself in this situation, the lender will most likely require other items in order to determine qualification before approving you for a mortgage.
