Distressed multifamily investing - capex, debt assumption and other consideration questions

Hey all - interviewing at a fund working on distressed multifamily deals in California and had a few questions. Would be super helpful if any of you have any insights on the below - thanks a ton:

1) This is a more general question, but if given the TTM, RR and broker presentations for a property, how do you project out Capex? Currently have separated the capex into vacant unit renovation/improvement capex and general maintenance capex. Have the vacant renovation/improvement capex projected out per vacant unit and have this trending downwards as a whole as the vacant units are filled and property reaches stabilization. The general maintenance capex I just have that per total units and have it growing 1-2%, in-line w CPI.

2) When it comes to sources and uses, is the general assumption that the new investor only has to pay for/assume the debt a correct one? I'm assuming if this is a distressed situation, the investor's equity has been "wiped out." Or do we still need to value the property using NOI/cap-rate and apply some kind of discount?

Thanks so much!
