I mean once you talk to them, it's pretty easy to spot if they know what they are talking about.I've work on STRs before and to be honest, it is not the most fun aspect of accounting because the volume of allocating income from all sources (airbnb, vrbo, stripe, direct booking, and so on) to a bunch of random expenses (cleaning, supplies, repairs, advertising, commissions, and all typical real estate expenses).I had to strictly rely on the client's input on what the expenses belong to which property or even units, if the paperwork doesn't say. 

I've done a lot of research on the topic and am familiar with the cons of owning a condo-hotel type unit, but the numbers seem way in favor of that vs a more traditional condo or SFH.

Im in a similar position with investor clients asking if I would manage their units for them. 

How many units as my answer depends on the number of units.  

The majority of that time is spent verifying rental income for the unit mix in the property.

I've been searching for residential multi-families in the $1M - $1.3M range to offset my mortgage by renting out other units.

We just bought a condo on the Gulf Coast, and the old management company has said the same snowbirds come to our unit every year from December 15- March 31.

I'm a STR manager and have a few arbitrage units myself.

It seems that when listening to Bigger Pockets podcasts, I hear the same logic, both from the hosts and the guests (mostly), that as a midsize (5-20) multi unit investor, Cash flow plays a secondary role to appreciation.  

Our goal is to close on a 10-30 unit building by the end of the year.
