I am an aspiring serial house hacker based in southern New Hampshire actively searching for my second small multifamily deal in the Nashua area, but I've hit a wall with inventory being so tight in my local market.

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.

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.

It's not to say I don't get sick and tired of stuff, but if it is worth it, I will continue to bang my head against the wall.

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.

Walls are priced one way, ceilings another, then you have baseboard, trim and doors. 

This has pluses and minuses.If your property is bulletproof such as no framing - cinder block construction, cement floors, gloss white paint slapped on the walls and a cheap window mount AC, then you are in a prime position to make money with S8. 

I would do some updates and add some color on the walls and maybe throw pillows etc.

That does not exist on wall street without an insane amount of risk and volatility. 

In some older neighborhoods especially historic districts, the tenants look for older houses - they preferred the art deco bathroom tiles, the thick plaster & lath walls over granite countertops and stainless steel appliances.but class D neighborhoods are easiest to tell.
