So I have recently listed my rental unit on various sites.

Once we missed the closing date, the seller wasn’t happy & demanded the EM of $10,0000 be released to him & put the house back on the market.We ended up with an extension only because we had been in a state of emergency and the lender had 8 more days to come thru & they failed us!

Most businesses, property management or not, fail due to the lack of sales, not due to the lack of systems and phone etiquette.

Give your guests high speed internet and smart TV's - they can use their own log ins for the streaming sites.

There is a ton of info on this site, as well as a meet up that others have mentioned.  

Also, as they say... not your keys, not your coins--so better have a very deep trust in whatever site you go with. 

This is probably a place where you go to one of the personal loan sites to borrow money or maybe a credit union. 

I highly recommend starting with a basic househack, easy barrier to entry and gives you a crash course in being a landlord who lives on site.

What percentages of businesses in that industry fail annully?

I have tried local governments sites with little luck.
