Now that you’ve defined the nightmare, what are the more probable or definite positive outcomes, whether internal (confidence, self-esteem, etc.) or external?

We were able to leave the deactivated K&T in the walls.K&T aside, if the building is old enough to have lath-n-plaster, I'd pick a inconspicuous spot along an external wall and make a hole to see if there is any insulation, or just another layer of lath-n-plaster in the cavities between studs {a common practice for a wind-barrier}.

You'll see the external factors that can effect price and you can't tell that by looking at a map or computer screen!

This "turn around" would need significant DD that would include evaluations external (uncontrollable) and internal (controllable) to the property in order to simply determine what would be a reasonable occupancy rate, and at what rent level.

From there I would do external views, you can tell a lot just from the outside of a house.That will greatly narrow down the possibilities.

No idea where you are from but we will often blow out the external wall.

Why not just call a locksmith to rekey the cylinders on the external doors?

I've also assumed an equal cost for unit #4 as my current rent, as I am going to move into this - if I rented it out externally, I would predict $1200 -$1250 in rent based on comps.ExpensesI'm assuming all other expenses are in the mortgage.

However, the debt terms are very favorable and the sponsor is planning to significantly increase the NOI (~250$/month per door) through internal and external budgeted renovations.

I figured that was the case but wanted some external feedback.
