Found a 3 storeys/units building in a mixed uses neighborood. Built back in 1865, it’s a structural maconery bulding (4 bricks wythes) with a flat rooftop. Each unit is about 1,200 sq.ft. and the biggest caveats are energy costs and some exterior features demanding extra maintenance (wooden openings, trims, old brick walls etc) Overall, the spot is nearly perfect, the price is fair (lower than average) and the lot is large enough (backyard). This place is actually rented as long term and Airbnb so, we can move in and have some income (get closer to FI). I figured almost 100k$ more than our actual house to buy and remodel (update) this place. Operating cost would be 5k$ more/year and income can range from 15k$ to 25k$/year depending how we rent the 2 units. Does anyone have experience with that kind of old building in cold (Quebec) climate? It seems you cannot improve insulation much without affecting the building integrity so, convertion from electricity to water radiator (gaz) or heat pump looks appealing. What do you think?
