I am debating about this because I know most people like mature trees but in this particular case, they almost completely cover up the front of the house. 

Each area has different rules, so it's crucial to get this cleared up early.

Has this ever happened to anyone?

This is very market dependent  also dependent on jobs and avaliable land to build etc.

This is what the site is made for, as well as for insurance displacement, travel nurses, etc.

Anyone with some background in this?

I feel like this is a trick question.......Aaaaahhhh.....

I’m contacted multiple times a week by individuals who buy lousy real estate in Philly and I hear “ but the agent told me” or “the wholesaler promised me” it was a legal use…the rents would increase…..I could rent this section 8 and achieve xyz rent etc. etc.  

I'd highly encourage you to reach out to folks providing value to other people in the forums and see if they're accepting clients at this time.

this also happened to some clients of fund that flip..
