Hi All,I have a tenant moving out and with that, it is time to replace some very old, single-pane windows and a sliding door. 

(address numbers, call an exterminator, fix the doors, take the crappy old fence down, remove the wall heater, cracked window pane, etc).

I really liked how nice it was and I got to know the neighbors and they're really great too.Purchase price = $31,500Rehab = $6,000 (approximately)Work done:+ Painting all rooms in the house (needed primer to cover ugly colors) + ceilings and trim+ New rainfall tub/shower faucet + plumbing+ New ceramic tile tub surround and tile base around the room+ New toilet+ New glass block window in the bathroom+ New windows in the entire house (except for large picture window), double-pane vinyl windows with tinted UV protection+ Basement laundry tub plumbing repairs+ New water heater+ Drywall replacement in upper bedroom around stairwell+ New outlets and switches in all rooms+ New light fixtures in two rooms+ New kitchen floor (sheet vinyl) also used on back hall and stairs to basement+ Miscellaneous (some new cabinet handles, smoke detectors, CO2 detectors, door knobs, new locks, curtain rods, curtains, light bulbs, grass cutting and gutter cleaning)Rented out at $875/month + utilities.The tenant I have is actually one from one of my other rentals. 

I dont want that old *** house with knob and tube, plaster walls, and single pane windows...

I did a flip recently where we replaced windows, going from single pane aluminum to double pane vinyl.

A tenant of ours cracked window pane.

Thinking about it now, buying more rental houses will increase my monthly income but could seriously strain my current reserves if something goes wrong. 

They look nice, but are the original single pane window. 

Oak flooring throughout with a generous dose of leaded glass and stained glass, everything single pane.

Ends of the peaked roof are called gable ends.I would remove the shutters, space is too small for shutters, and install vertical vinyl siding, in a light pastel colour with a wide white trim around the windows.I would install new windows with divided panes.
