I totally apologies to anyone if I  offended you,  for I was blind sided and miss lead.end of story.........moving on

I'm not sure what your legal or moral obligations are in this instance but it may be worth considering given that you know how it feels to be blindsided by this issue.

We were blindsided by the property taxes on this property and disappointed in our realtor not knowing we’d have to pay a homestead tax since we didn’t live in MI (basically doubled the estimate - leading to the lower return rates) Lesson learned for sure.

Obviously there is a lot of variables to this depending on the situation, the property, and what the seller has told me about each specific tenant.  99% of the time the tenants know they are way under market and will expect it to be going up after the sale so you probably aren't blindsiding them, they know its coming. 

Tenant promised to pay me rent by today (aug 28) and blind sided me with message she is moving out. in 2 days.

I would speak with your neighbors beforehand and try to get in touch with the alderman so they are not blindsided by the letter.   

Don't blind side them any closing when they realize your entity isn't on the buyer's side of the settlement statement 

We were blindsided by some false accusations from a disgruntled former employee...I just remember that even though we won that mediation, in many ways we lost.

I say that because you wouldn't want to be blind-sided on some of the things that you need to watch out.

Don’t go into the process blindsided and get pre-approved from a lender quickly!
