And maybe they are... but if I get my investment back and "anything" above that, I'll consider it a worthwhile experience.

I found myself immediately withdraw from sharing anything worthwhile that could help this guy.

If, and when I expand my rental investment to more properties in the future, then a commercial umbrella policy for the LLC may end up being worthwhile (or alternatively, I could look at establishing 1 LLC for each property to segregate each property).

If $25k is an easily affordable amount for you and you want to ramp up quickly it may be worth while.

If the technology is good then it may be worthwhile.

If the costs aren't that high, then I'd consider it be a worthwhile expense if it means that it will get rented faster.

If the bulk of your rentals come in via Airbnb then it might be worthwhile to pay for the data you need.Before these tools were rolled out I had a spreadsheet with links to some of my competition and I would see how full their calendars were and what rates they were charging.

Haters gonna hate.There are a dozen saying that go something like, "if nobody is criticizing you, you're not doing anything worthwhile."  

If you asked me to re-use each piece I'm probably going to charge you enough in labor to make it worth while to get at least new skirting panels and try to reuse the skirting kit.

Working 3-4 hours per day, 3-4 days a week to double the amount of money I make from the rentals (cash flow alone) seems a worthwhile endeavor and no-one will manage or maintain my property better than I can.
