As someone who is still very new to STRs I'm wondering if a service like Minoan would be worth it or too much of a hassle for newbie getting their other systems locked down. 

He was there for a very short time, then I locked up the unit.

If your rate was locked, then yes.If your rate was not locked, then it depends.

She is in a big beautiful house on Parkside Drive with a wing that can basically be separated off by a locked door, but her wing doesn't have a kitchen.

I have a SFR close to Wake Med that is nearing lease end and am all ears.

Find yourself a good local housekeeper, treat them well with the occasional bonus and they will be your eyes and ears. 

Hopefully by now you've locked in your first property and are cash flowing nicely on it.

Everything Ken said plus plaster walls, no insulation, higher electric bills, walls sweating when its humid in florida and the resident leaves front door open, damp smelly houses, Pealing paint, wood rot, old windows, crawl space under the home, bdrm and closet doors that don't close properly, electric locks that the old front door doesn't like as the door is not aligned correctly, Cyrstal knobs that fall off, old thermostats with 2 lines but my new thermostat needs 3 lines, critters in the fireplace....

@Alex Ko The ADU construction capital getting locked in the property at this time doesn't necessarily mean it doesn't work.

I'm a licensed Realtor who represented myself in this transaction and I negotiated a $15k seller concession I used for a 1-0 buy down so my rate for 1 year will be 5.99% and then revert to 6.99% for 30yrs. and then we used the rest of the concessions for closing costs. in 6 months or 12 months I will revisit to see if mortgage interest rates dropped significantly to justify a refinance to lock in a lower interest rateone more question.
