Just going to add a door and closet to an addition and BOOM, 2/1 turns into a 3/1 = forced appreciation.

I've had two occasions where the reference they listed told me not to rent to them because they were violent, late payers, or too needy.Not doing a criminal, credit, background check, which might have revealed criminal or credit problemsBeing slow to evict (mentioned by others)Believing their sob storiesAccepting partial paymentsFailing to document every conversation or interactionNot walking through the property to make sure they're taking care of it (I now walk through every 9 months so I can see problems in different seasons)We've found crack pipes and other paraphernalia after they moved outWe've discovered piles and piles of trash (some bagged, some not) in closets, basements, sheds when trash cans and pickup service are included in their rent - all they had to do was carry it out, at no cost to themWe've Found smokers, pets, extra peopleOverall, I've had great success as a property investor. 

The report confirmed presence of lead, mostly windows/doors, but also mentioned closets and a few other areas.

So you provide the cabin supplier, arrange all necessary connections and permits then hand it off to a PM and charge a fee for your services.So to do that all you need to do is go into local council and establish what the rules are for portable dwellings.

Even if you have two big guys, the water heater might be in a closet so the guys can't fit on opposite sides to lift it.When I replaced my water heater, I modified the heater closet. 

You should definitely put a closet in there so you can advertise it as a 3 bedroom though. 

At walk through, fan blades were all caked with dirt, cobwebs and dustbunnies abound, hardwood and tile floors hadn't been swept or mopped, countertops not wiped, exterior of kitchen appliances not cleaned, stove top still semi dirty (stove was brand new a year and a half ago but she claims "it wouldn't wipe off"), kitchen sink with soap debris on it, food stains splattered on kitchen backsplash and baseboards, bathtub not cleaned, closet floors/shelves/blinds/windows not wiped down, and my favorite - remains of a carcass of a hawk (feathers and...?)

In addition to the above, with older homes you may see functional obsolescence issues... no central HVAC, single pane windows, small closets, small rooms, single (one) bathroom, etc.

The entire servicing history and payment history needs to be completely portable from investor to investor and servicer to servicer.

The lone bathroom was a really weird arrangement with a beautiful vinyl accordion door which blocked access to the only closet in the bathroom when the door was closed (ie:: if you ran out of TP you had to open the bathroom door to get more...)We decided to make this bathroom part of a 'master suite'.
