You area will likely have different regulations I just use these as a n example. 

There's not as many regulations if selling to another investor non-occupant. 

He will however not stop although he will promise to do so.I suggest you study your state regulations and, based on your assessment of this tenant, terminate his lease a soon as allowable.There is no point in attempting to deal with the smoking if you do not wish to keep the tenant unless you are stuck with him due to the term of the lease.

When you have a license you are bound to all the rules and regulations that go along with having that license and that includes disclosing the fact that you are a licensed agent.If you are planning to buy and sell land off market, you will just need to make sure that all parties are aware that you are a licensed agent but only acting on your own behalf and not representing any other interest but your own.

You will not have another late.If your state regulations do not allow this you either properly manage the property, turn it over to someone who can or live with late payments.

What it means is that more landlords will be breaking the law knowingly or unknowingly in most cases.In our jurisdiction because the regulations are so tenant friendly operating and protecting our business interests make it almost impossible not to bend the law to the limits.

Study up on the different zoning regulations/restrictions for each zone at: http://handbook.dcoz.dc.gov/That should help you better understand the MUs as well as identify which zones will allow 4 units.

This is all so new to me, I am really unclear on the rules and regulations with down payments in Ontario, Canada.

I don't know what your exact plans are in terms of flipping or holding but Airbnb has treated me well here and I plan to keep expanding on that (most likely in the Downtown area) especially since Fresno is WAY under the radar of Airbnb regulations.
