I remediated the tenant situation immediately upon closing and have managed it successfully since with that same tenant in place!

I self manage my own rentals and I also operate a management company assisting other investors nearby. 

My company was only a couple of years old at that time, and I was still working a full-time job (working two full-time jobs, really).These are the shirts of men who have to get dressed for work for the day, going into the office from 9 to 5, so to speak.At that time, I was one of those men putting on a shirt and tie.

Obviously the ADUs are capped at 750 SF.My client and I are pursuing this option now! 

I own 2 units and manage another 2, we're seeing 5-15% vacancy across the units over the past 18 months.

Are they a massive company or a smaller boutique manager?

I recommend building your "core 4" (Real Estate Agent, Property Manager, Contractor, Lender) in your target market.

Number one thing impacting vacation rental success is management. 

My class C rentals this is a common scenario and I have this situation frequently.

The BP community has been incredibly helpful for a newbie like myself and I appreciate everyone who has taken the time to comment.
