Rental stress test algorithm help

[Victor L.]

Hi all,

I'm currently working on the planning phase of creating a rental stress test algorithm that will essentially output the inflection points where the deal turns from good to bad. The idea is to eventually have it running with a click of a button given certain criteria as I'm running the numbers on a property. I'm primarily focused on SFH but any MF advice/opinions is also appreciated.

The possible cases I have so far are:

-Vacancy (how many months can the property hold before the numbers turn negative)

-capex (how much monthly income can I put aside while still getting at least $100 in cashflow )

-declining rents

Thanks in advance.
