Electric: is the easiest to split, but may require holes cut in walls to separate the units.Gas: gas lines aren't as flexible as wires, but it can usually be done affordably.Water: most cities will NOT install additional water meters on a property.

I would also cut down on the photo count.

It was a huge investment, but it cut the electricity cost by the full 2K per/mo all summer.

The flooding cuts both ways. 

A HELOC comes with a variable interest rate and all signs are pointing to no further Fed rate cuts in 2025 - and there may even be rate increases.- So, you may want to consider locking in an interest rate via a 2nd mortgage.Do you have reserves for unexpected expenses?

This business is cold and cut throat.

If you use a PM, you are cutting heavily into your profits.

As long as you're doing that, there's always a risk, and 50 years from now it will probably be illegal everywhere to operate STRs in residential zoning, just like it's illegal to operate a steel mill there. 

We Normally put steel posts nearby so no one runs into them.In the third picture one unit is just in front of the picture, then a second unit is at the far end on a post.These can be set off by deep fog, rain or sleet. 

There are regulationsI could go on, but if you learn this much, and apply it appropriately, you will cut down your sorrows and risk, considerably.And yes, there is much more.
