I highly recommend adding at least a monitor if you plan on making digital nomads one of the guest avatars that you're marketing to. 

There are double digit net caps to be had 100% hands off.......

You need to get licensed plumbers with the proper equipment to first of all examine the entire run via camera, then they can advise you on what can/cannot be done.

Some may be comfortable with 100% crypto transactions, while others could opt for a split between cryptocurrency and cash.For sellers unwilling to receive cryptocurrency directly, the digital asset will be converted to dollars to complete the transaction.Once terms and contingencies have been agreed to by the buyer and seller, the transaction process is the same, except that you'll need to work with an escrow service that is willing to or has experience handling cryptocurrencies. 

Things like CCTV cameras, signage and exterior lighting go a long way with tenants.

I use a lock box, Wi-Fi thermostats and a security camera I can check on remotely.

Moreover, with the rise of digital nomads and long-term renters, you have a brand new clientele for international properties that pay high rents and give you 100% occupancy.

In summary, the main building:1) will need to be tented for termites/ants,2) will need basically two full bathroom renovations (floor around one toilet is a bit soft and rotted some of the joist down below, and the other bathroom is an addition that looks like it also might not have been built to code bc has really tight spacing and has a huge crack in the walk-in shower that basically just drains water out into the crawl space below the house and the floor under that area is just totally rotted out),3) would need a refreshed kitchen (sink drain plumbing is in need of repair and at a minimum would need new countertops but likely new cabinets as well)4) they recommended earthquake bracing to the foundation since it’s almost a 100-year-old house and reinforcing part of the cripple wall down below5) found a clog (or at least an area the camera couldn’t get past) in the sewer line.

We have trash day reminders, check-in instructions, house rules, check out instructions automatically sent to each guest.. it also changes the door code to the last 4 digits of the guest's phone number for each guest. 

However, 99.9% of the math you'll need to be able to do with real estate you will have learned by 8th grade.The real estate agent that just sold our house in NY could barely bang out an email and it would have killed her to have needed to add two 5 digit numbers together.
