Good morning BP community,I recently got my real estate license per my dad's advice (who has been an agent for the past 25+ years) and I really want to get my foot in the investing door. He has suggested to me to go i...

It also has an additional 600 sq. ft Den with an outside entrance that could be converted into an apartment.

I was trying to get a wash and he was at the entrance helping work his cash/card acceptor. 

May not be a detached ADU but you can find properties with unit above attached garage or separate entrance to basement MIL guest suite. 

They can also do custom jobs where a tenant has a key for their unit only but it is also works as a common access keys (for storage, pool, main entrance).They also sell special screws that are tamper resistant.

From that point we pull cell phone data to tell us where people are coming from, where they are going after, how many visits that person has per year, and even what entrance of the plaza is used most frequently.As far as telling you what we know about them, we know quite a bit, we own and maintain a database of over 17K urgent cares nation wide, and even provide that data to the National Urgent Care Association for their articles and studies. 

My understanding is that the 2040 plan makes it so that zoning can be changed to accommodate triplexes anywhere in Minneapolis, but along with that comes more stringent building codes that are compliant with commercial code instead of residential, so fire and soundproofing are required.To answer your question, I'm fairly certain that an ADU requires a separate stairway entrance.

It is not formally duplexed, but there is a separate entrance to the basement.So how would I go from SFH rental to SFH with personal use of 1/3 of the house and rental use of 2/3 of the house?

Before I put in an offer, I want to run the numbers by some professionals.The property is 4BD/2BA in total, with 2BD/1BA upstairs and 2BD/1BA downstairs with separate entrance.

We know the upstairs is already set up nicely as a duplex with front and back entrances.
