However, the Smart Move Team recommends looking at PDA Investigations (takes ~3 business days) to access the non-instant criminal records.I hope that is helpful.

My questions are; When it comes to notifying them that their leases won't be renewed what's the best time frame; 30-60 'business days' or 30-60 days (including weekend and holidays)?

If your rental is unfurnished I will be providing rental furniture for the client, so please make the lease start date at least 2-3 business days from the day you’re sending it to me if possible.

To initiate in Michigan I have to mail a 'Demand for possession' through first class tracked mail and then wait 7 business days not including the day it was mailed in order to file with the court.

@Marcello D. 10 business days

Just for rent collecting and screening.. rent collecting is free but takes 5 business days to receive payment.

Often it mandates the turnover of documents and return of funds with 5-15 business days. 

If Earnest Money was due by a specific date and never paid, then technically your buyer was out of contract the next business day that the EM wasn't paid.

If it is in the lease that they must have it I would ask them for proof that they got it and if not insist that they get it on the next business day.

If she does not accept your offer, then you can begin filing on Tuesday (the next business day) and you know that you offered her a way out.
