Now, if you are in a rental situation where there is continuity between all the rooms already and you are looking for the next level of pizzazz, you can update old laminate counter tops with new laminate counter tops, lay vinyl plank flooring in the kitchen and bath, spend a little more on bath and kitchen light fixtures, add a few USB charging outlets, install ceiling fans in bedrooms instead of flush mount fixtures (but remember, more moving parts means more points of failure which can equal more maintenance calls - however if you are getting better tenants and higher rent, maybe that doesn't matter - I personally try to remove points of failure - spray hose from sink, ice maker from freezer, garbage disposal, really anything having to do with water).

You will need a license heating & air conditioning contractor to install unit.If your are providing the heat at your expense, there are certain minimum temperature requirements by law.

Many times historic preservation committees are only concerned with the exterior appearance of the building, meaning you may not be allowed do things like add onto the structure, use vinyl siding, and you may be limited on the style of doors and windows that can be installed, etc.

@Bjorn Ahlblad, what model washer/dryer do you have installed?

Even though the paint and carpet are brand new, installed just before it was listed, it states they need to be replaced.  

Then re-install the door.If it is an interior door, one of those cheap hollow ones, you can remove the door and drill new holes for the screws in the frame.

(Installing a furnace, replacing siding,...)ie.

Most people told me they were surprised at how much work it is, and how long it takes to gut a home.The next meeting was a "Flooring Installation Day". 

Hi,I have a tenant who wants to install a Security Camera to record Video only, on the Front door, mailbox and a Driveway (includes 3 feet of the public walkway).Is it legal in Maryland to Install Security camera on the front door which can also capture Driveway and some common area?

Basically, buy an acre of land, run utilities to it, install four prefab (I think 800 Square Feet is the max) park-model homes/tiny homes and then sell 3, keep 1 for rental.
