I agree with @Cam Schumacher, I'd go the Nomad route, which is where you buy a place as an owner-occupant, live in it for at least one year, move out, convert it to a rental and then repeat.

We also converted a very very large laundry room into a stackable laundry and 0.75 bathroom.

I then convert the spreadsheet into a book and print it for workers.

I keep it zoned as a 2 (2 gas and electric meters) so I can convert it back some day when the kids are out of the house and it's easier to go one way than the other.I was thinking of putting in a "temporary" kitchen for the purpose of the appraisal but not sure what exactly I need to have in there..

HelloLooking at a multi family that will be converted from a 2 unit to a 3 and in need of a full gut rehab in the Brooklyn, New York area. 

I would do most of the repairs myself except for converting that room. 

You can probably convert to a 3 family (check and see if there are any other 3 families permitted on the street- the tax records will tell you) but it will likely require a lawyer and a decent amount of time and money.

Several things worth pointing out, your down payment doesn’t lose its value when it is put into a property, rather it is converted into equity.

My home currently comps for around $330,000 and I could potentially convert it into a duplex. 

I closed on my first self storage facility at the end of April that has been run by a manager using spreadsheets, and I’m considering converting everything to an online management platform.
