AirBnB has been the biggest surprise. 

Also, my biggest question on the IRRRL is does the IRRRL just lower to whatever the current market rates are?

My preferred options are:1. house-hack with a duplex under ARV; live in one unit => renovate => rent the other unit2. buy a SFH under ARV that could be converted into a duplex (preferably adjacent units vs top/bottom) - I'm assuming the biggest challenge with this strategy would be separating the infrastructure for utilities; and costly.

The biggest lesson?

This would apply to your unit.Your biggest concern with setting the rent should be the near future. 1) Your insurance is guaranteed to go up, probably dramatically.  2) You may get an insurance assessment bill to cover the CA Fair Plan losses.

One of the biggest lessons I’ve learned: if the sliding door is broken, call a sliding door specialist.

My biggest frustration isn't with the deal failure itself, it's more with the operating performance of the GP and honestly I'm not sure how an LP can really determine this.

My biggest concern is just having boots on the ground in case something goes wrong.   

Our biggest expense was replacement vinyl siding, which costed around $40K.
