I didn't know at the time of purchase, but it can be a deal breaker (from what I've been told by several contractors) on putting up recessed lighting.

My software allows me to be logged in to several Airbnb accounts at once and it brings it all into the unified inbox.  

As well as they expect free health care . 

But really you’re just creating a second job for yourself and one that doesn’t pay very well if it even is cash flow positive at all 😆I used to buy houses for STR but now that I’ve got several STRs up and running that I bought many years ago, I stopped buying STR once mortgage rates went up and housing prices went up.

As Stuart mentioned, there are several issues that might arise with the property, which could definitely impact your cash flow. 

Similarly, if you put several Class D tenants in a Class A 4-plex, what do you think will happen to the property?

I wrestled with trying to turn that into a short term rental in my mind several times.

There are several companies that send letters and some are active on Bigger Pockets.However, I would caution you to set expectations appropriately.1.

Me having several thousand good reviews help, but personally I would not book a property with 0 reviews. 

We recommend you get management contracts from several PMCs and compare the services they cover and, more importantly, what they each DO NOT cover.
