In the 6 months I'll be doing some rehab (paint, floors, some fixtures, new island, etc.).

The annual rent increase is limited to 3.5% a year, however this year, we've spent about 35k in new siding for the building, a new floor for her apartment, a new fan, new stove and hood. 

Assets identified in this study include:Appliances: Dishwashers, laundry machines and refrigeratorsElectrical and communication systems: Specialized equipmentCabinetry, Countertops and shelvingInterior Finishes: Laminate flooring, carpet, and decorative elements.Security and communication systems: computer connections, alarm systems and telephone connections60.8% of the total depreciable basis was classified as 39-year class life.

There will end up being 4600 sq ft of floor space for all buildings combined.

*Note that we interchangeably use the labels: Lodging House = Rooming House = Single-Room Occupancy (SRO) = Co-Housing PropertyThe building has 3 kitchens and 4 full bathrooms, on 4 floors:3rd floor: The 3rdfloor is ‘off-limits’ to the 1st and 2nd floor tenants, so the two 3rd floor tenants enjoy the exclusivity of their own entrance, and a kitchen and bath shared only with one other unit, plus some distant ocean and Boston skyline views.2nd & 1st floors: Eleven units share 1 kitchen and 2 full bathrooms, one on each floor.

However, during my time there, my landlord was living happily near the beach with a big home, a new BMW, and a 36-unit apartment building (3 floors, 12 units per floor).

I rent the second floor for 2100 which leaves me with the remainder payment of 1132.Am I generating cash flow since I have approximately 65% of my mortgage covered by the tenants?

Will all floors need replacement if I take them all up to work under the house or can a reuse the floors (they are hardwood floor, old and need some refinishing)Of the steps needed, what are the most DIY friendly for a newbie like me?

A big trick is to do cosmetic updates to max out the rents, for example most deals I sell we raise rents a good 30-100% after paint, new counters, new flooring, paint/replace cabinets.

I already know I am going to have to replace all of the hardwood floors and probably the subfloors.
