I filled up the walls with "open cell" spray foam insulation. 

I would spend the extra money on foam insulation in the rafters, keeps things very energy efficient and only put insulated batting in the exterior walls.   

The asbestos will tend to crack when you nail siding over it and some people like to put half inch foam board over it first.

If you are using closed/open cell spray foam, you need to make certain the bricks are able to breath and dry - otherwise they will spall - so normally you do not want to apply the foam directly to the brick.If the building is structural brick, then there may be an internal framing for walls, but more likely there will be furring strips attached directly to the brick.

If there is not, then you should be able to blow packed cellulose or closed-cell spray foam into the wall cavities.  

@Rashad S. have they looked in to a HELOC?

Best to tear up the existing HW and lay your new floating floor over that (with the appropriate vapor barrier/foam padding).

I am assuming this auction is taking place because the mortgagee(s) have died and the loan has not been paid for a while, the bank is forcing the sale, not the pr?

My first flip went similar to yours; if I were to go back and do the same project now I would probably shave $15k off the rehab and do it in half the time.
