Cities usually don't care if the OWNER lives in the basement, just tenants.You could use the extra income to offset cost of finishing basement and more.

Anyone else having this issue or his an isolated issue?

My intention was to see how this rate compared to the IRR of a SFR investment using several property assumptions and different purchase models.

@Gary R UrenIf the property is zoned for only one home you most likely will not be able to do thisPossibly it could be 123 main st unit a vs b but that is a post office issue and good luck dealing with the post office on this issueI would talk to them and put to mailboxes in the front and see if they can separate it by A and B unit

I personally use propwire.com for residential lists but you can get them online from tons of places. 

Is this the case?

This protects you from potential scams.

Hello BiggerPocketsI’m excited to introduce myself as a new member of this vibrant community.

We are looking to close on a property towards the end of this year or at the start of 2025.

If you buy a duplex and your "cost" per month is 750 (just using a number) but for you to rent or (even buy) a similar single family it would cost you 2000 a month then you are still 1250 a head every month!
