I'm working on my first rental and trying to understand the best practices for how to use the template leases I can find.

I've just watched the "gator method" today.

Yes, the BRRRR method can work with multifamily properties, and many investors have done it successfully.

Is there a formula to understand whether a real estate is class C or not?

I get a lot of questions about housing vouchers and how you determine rent amount allowed.
Each housing authority (HA) provides a voucher amount determined by bedroom and some further define it by zip code or city w...

This depends on if you are using the Cash or Accrual method of accounting for tax purposes.

But why would that make them want to use this financing method?

I'd send out 500 at a time, using a different mailer/method weekly.

BRRRR method is also a great way to go - good luck!  

I was going through the rent control laws ( I know, should have done that before purchasing the property ), and a section stands out. https://ecode360.com/30526708#42037155Based on what I can read, the rent control chapter doesn't apply to: Dwellings of three and four units, at least one of which is occupied by one or more of the owners thereof.My understanding is that rent control doesn't apply to owner-occupied multi-units.
