Even if you manage tenants yourself, you still have to set aside for CapEx (20 yeas old dwelling) and maintenance. 

Also if I split the two dwelling I would need zoning for dual-dwelling.

My rent was skyrocketing, I realized I could never afford to buy a primary dwelling in the area of Seattle I desired, none of the investor numbers made sense, and my 12 minute commute into downtown was quadrupling.

I've been in the Factory built housing industry as a California general & manufactured home contractor, manufactured home dealer & developer, California real estate broker, property manager and investor for the past 50 years in one capacity.I a currently negotiating the exclusive distributorship on a line of Prefab Accessory Dwelling Units (ADU's) aka granny flats, Tiny Homes, etc.

Just file eviction even if they are paying since it is against a locality regulation to have that many people in that dwelling?

If I may add, Never by no means ever waterproof or try and correct the issue with interior drainage systems, think about it your still allowing moisture in the basement, if anything now your increasing moisture from entering into the dwelling because now you just exposed below the foundation floor, its a cheap way of putting a i guess you can say band aid on a more serious issue.

I agree with Nathan - if you have an area you both like and could find a duplex or a home there with an accesory dwelling unit, you could live in one side and rent out the other and pay the mortgage, and if you decide to move elsewhere one day, then you can rent out both units.    

Requires a landlord to register all dwelling units with the Illinois Housing Development Authority by January 15th of each year.

You set up Tracking Categories such as Dwellings or Houses.

I would like to create a business where I connect people who have excess land (the tiny house would be a second temp dwelling in most cases) with people who are looking . kind of a cross between wholesaling and property management.
