New Landlord Questions

[Nicole Chaput]

I have 2 properties I am looking to rent soon and planning to turn it into 4-5 rentals in the next year. I have a few questions. 

1) Do you legally have to go through landlord training in your state to do this? Any recommendations?

2) Property I am looking to buy in Massachusetts is listed and being used currently as a multi family, however it is zoned as a single family only. What kind of problems could I run into in the future because of this issue?

3) Should I try to get it re-zoned before purchase? Could this open me up to more issues?

I appreciate any and all feedback.
