This is more of a commercial real estate rule of thumb and I think it is less applicable to small multifamily 2-4 unit properties for several reasons.

Is your DSCR ratio greater than 1-meaning are you cash flowing (according to the lender's criteria of mortgage, property taxes and insurance (and HOA) if applicable).

In my opinion, all have a general relevance for educational purposes to elevate your status within an industry, and this is applicable to most.

CRM's are typically "add-ons" for real estate software making them half baked. 

The demographics of these investors are typically high income earners, almost 90% working in tech (software engineering, tech sales, computer science, etc).

We pay them back at close.For people/teams that do something similar, I'm curious what software you use or spreadsheets you've created to: Track cash current cash flow and projected cash flow for the whole business that including fixed costs like payroll and variable costs as well.

Can take up to 3 months to go from application to lease.

HI Vincent,Correct DSCR is only applicable towards investment properties and you need to own at least one property in order to look into DSCR.You can always start off by house hacking meaning you live in one UNIT or ROOM and renting out the other vacant units/rooms to offset your monthly mortgage payment.There are several ways to run and make sure you are maximizing your rental income while keeping your living expense as low as possible.

Use accounting software and hire a real estate accountant to do your taxes.
