@Parag Doshi the 2% rule doesn't work in most areas at this point in time, many investors have moved to the 1% rule, but the problem with both is that they are too broad and people try to apply them nationwide with no regard for the intricacies of a particular market. 

@Andrew Aladjadjian is correct re the new owner occupancy law, I would just warn that I have a few clients who built ADU's in LA (SFR) and now the cities rent stabilization unit is trying to call it a multiunit and apply rent control to their single family homes. 

1) It is not yet clear but it seems that you will be grandfathered in at the time when the changes occur in regards to occupancy changes.2) Per AB-68:"(A) One accessory dwelling unit and one junior accessory dwelling unit per lot with a proposed or existing single-family dwelling if all of the following apply:(i) The accessory dwelling unit or junior accessory dwelling unit is within the proposed space of a single-family dwelling or existing space of a single-family dwelling or accessory structure and may include an expansion of not more than 150 square feet beyond the same physical dimensions as the existing accessory structure.

If they have over paid that can be applied as a credit against future Additional Fees. 

I've found the same advice applies to tenants and PMs "if you think you need to end the relationship, then you need to end the relationship". 

Curious if anyone has ever applied for a rooming house license?

My mortgage broker shared with me that I could also apply for FHA at the same time and thus I would pay only 3-3.5% down if I purchase a duplex.

After the second property, I started taking any side hustle money I made and applied that towards student loans while saving the same amount from my W2 and rental properties.

I have calculated a ball park ARV based on Zillow comps and reading my appraisal of the home before remodel and applying methods the appraiser used.

This one doesn’t always apply.
