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.

Install low profile LED lights or wall sconces.If this is an investment property you need to be thinking about returns.

When I subsequently asked the tenant over the phone how many cats she had she said four, which is likely half the number she actually has, but is still a lease violation.At this point I feel like it’s pointless to even ask if the cats are neutered (and therefore less likely to spray urine on walls) because clearly she is willing to lie to me and her attitude seems to be that she makes the rules not me or the lease.

The previous owners took reservations mostly by phone, wrote them on a big paper wall calendar and hand keyed CC numbers into a terminal 😲The bunk beds have been a huge win.

Improvements that DON’T drive the ARV as much: Windows, Landscaping, Driveway, Rough Plumbing & ElectricalI agree with @Jaron Walling about meeting the appraiser at the property and providing documentation.

Glazing in walls, enclosures or fences containing or facing hot tubs, spas, whirlpools, saunas, steam rooms, bathtubs, showers and indoor or outdoor swimming pools where the bottom exposed edge of the glazing is less than 60 inches (1524 mm) measured vertically above any standing or walking surface shall be considered to be a hazardous location.
