You can dig any roots in your yard . 

My gardener went to remove a tree that was growing roots underneath the foundation, and when he sent me photos, there was cigarette butts all around the back patio and front of the house

The fact that the buyer made their payments will not prevent a foreclosure. 

Rooting for you. 

(Williams in Greensboro was only charging me for the trip fee but I elected for preventive service since they were out there anyway.I'll pay more attention to my unit air returns in the future. 

A tree root had grown into the sewer line which became an issue once I got renters in the property who were using the showers/sewer regularly.

Quote from @Elisa Lisa p: Thank you Greg, the neighbore upstair has avoid 3 times in past 10 years to my ceiling, I really think is his responsibility that his radiator leaks.should I just take the neighbore to court and not get HOA involved.Since the leak is going through a common area and they have made no effort to prevent this, I'd include them.

However, large volume wholesale companies of which I'm aware tend to have non-compete agreements that you must sign, which would "prevent" you from going into business for yourself (or with a competitor) for some period of time and/or within the same territory.

I don't know how planted your roots are in NY but it may be beneficial to go house hack in a more affordable state.

I.E. do exactly what they are trying to prevent.
