We also used the opportunity provided by the extend of the demolition to do the following:Install a free-floating, insulated (R10) subfloor (a first for us) over the slab on the main level;move the laundry under the stairs to the second level - a better use of space than the deep sloped ceiling closet that was there;resize kitchen - we made the kitchen 42" longer, but this necessitated moving the electrical panel into an 18" upper cabinet;reconfigure the bathroom - with the laundry not moved out of the bathroom, we made the bathroom a little deeper (about 6"); moved the toilet slightly; shifted the tub about 18" and moved the vanity to the other side of the room;reduce the size of the living room window to an 18" transom window giving much more usable wall space;replace the broken windows with Energy Star certified windows tuned for their exposure;build an entertainment feature wall on the living room side of the stairwell.open-up both sides of the stair well (living room and hall by bathroom) - this allows for better air circulation - a necessity when we install the heat pump.Here are a few select shots of the process:Demolition begins:Repairing sections of wall:All electrical and data network runs were installed, then next came the insulation:We finished shifting our plumbing and patching the slab.Next we "leveled" the slab ... ok, we made it better ... and laid the subfloor:Note that we installed 4" high, plywood spacers around the perimeter to keep the floor ~1/2" away from the external walls.

We take a very data driven approach to our investment strategy and opt to acquire a couple really good asset vs. a larger amount of assets with average returns.

Is this enough info to call a local, very experienced and well-funded flipper and offer a partnership on the deal if it can work, or do i need to make sure it can work first and provide numbers, photos, comp data, repair estimates, etc.?

I appreciate your thought and wholeheartedly agree with your underlying premise of making business decisions based on data and analysis.

Hey BP team - I'm wondering where most you get your market data when you are looking at market trends, prices, growth, etc.Do you pay for it?
