You can still get identical results you calculate based on the assumption there’s a 30yr mortgage on the property

“Of all the preposterous assumptions of humanity over humanity, nothing exceeds most of the criticisms made on the habits of the poor by the well-housed, well- warmed, and well-fed.”Herman MelvilleSo much to unpack in your other comments as well, Jill, especially on build quality.

All you can do is underwrite the deal using your assumptions and decide if you want to proceed or not.

When a property built in 1988 has the original air condition condenser, it is a safe assumption that the cap ex will be cashed in sooner rather than later.  

Rent Assumptions Increase: It seems some deals assume a unrealistic rent assumption increase either based on the value add, or the annual increase seems unrealistic. 

@Sean HollandNeed more information, so will have to make assumptions.First assumption: you're trying to flip houses.

Again, others might feel differently here.3) property level due diligence: (takes seconds to weeks per deal): here is where I drill in with the low-level details.a) pro forma popping: I examine all the assumptions, and see if they are overoptimistic or not.

You are operating under the assumption that everyone wants cash flow. 

@Ray A Delfi - I obviously only know what you have told me so I have to make some assumptions. 

I am looking for anyone to poke holes in any of my assumptions or provide feedback on things I may be overlooking.
