When the other side of the transaction needs to reach you for signatures, disclosures, offers, showing instructions, etc, you're probably tied up at your full time job.

I instruct them to use hair traps, food traps, lint traps on dryers, etc.Preventable damage caused by things that may not be the tenants responsibility but that they didn't report in a timely fashion: An example would be things like the roof leaking, or the presence of those house eaters I previously mentioned.

If it's not returned by the deadline, then I send the tenant a notice that their lease will terminate on 11:59PM on [DATE] and include cleaning and move-out instructions.

They’ve developed an app for STR owners to input our cleaning schedules directly and even provide any specific instructions.

Good restaurant menus, special  stores, fliers for experiences like zip lining, contact info for grocery stores, or what ever.You could add some check out instructions on the fridge.

It's in mixed zoning, and I have already confirmed with county I can rezone it to commercial and received all the instruction on how to move forward with that process.

Had I not called my friend about the other listing, I may have never found this property.Regarding communicating with the tenants, I just sent them written notice prior to closing that the property was being sold to new owners and new instructions on how to pay rent, then after collecting the first months rent (as a reserve), I sent a follow up letter letting them know that their rent was being raised, and just waited for calls to come in.
