Call and find out how much they owe and get permission from them to talk to the lender.

I used to think that, however, earlier this year I contacted several lenders for pre-approval letters and they all asked for permission to run a credit check since they were doing "hard" checks...

And always ask for their permission to follow up and see how they're doing -- get their info (as much as possible email, address, etc) and put them in a follow-up campaign and keep contacting them!

And if you are the third party that has bribed Zillow for leads through this bait and switch mechanism- don't sign people up for your mailing list without their permission. 

And he trespassed when he entered your building without permission - how did he get in? 

2) If so, did you get the written permission of your lender?

I am not looking for additional employment...just investment opportunities... but would prefer to not have to get formal permission

If you see 3 beds and 2 baths, and the prospective tenant sees 3 beds and 2 baths, then it gets rented as 3 beds and 2 baths.What I would be concerned about is whether the building department is going to issue some kind of penalty or require work to be "undone" because the work was done without permits.It sounds ridiculous, but that kind of thing happens, especially when another whole unit is added without permission, and even more so if it's added in a potentially unsafe area like a basement or a 3rd floor with no fire escape.So that's why I'd recommend explaining the situation to the building department and asking whether it's something you need to be concerned about before buying this property.

My tenant put up a satellite dish on the roof without my permission just DAYS after I had just put up a new roof on the property.

I don't want to use his name publicly without his permission, so perhaps we can DM each other to confirm if that is the case.Anyways, all of the above comments are spot on, he should be benefiting from the deals but you should also do you own due diligence on everything too.As I mentioned, feel free to send me a message and we can connect that way if you would like.
