@Matt OwensWe have several members who live in the Grand Rapids market, and own assets.

In my area, not only is there zoning regulations, but building regulations where 3 families are built to different building standards, such as cement walls for boiler rooms, sprinklers, fire escapes to name a few.

You could get roommates to rent the extra rooms?

Is there room to renovate/did you renovate?

@Kevin L. buy a home that you can improve and add value, including turning the garage into an ADU.Also, take the ugliest room and rent out the rest to generate income to offset the mortgage payment or to accrue cash for improvements or additional investments.

I like Casa Grande, AZ for this, we have new builds that are around $300k and will rent for around $1750/month. 

Make sure that there is enough room for investors, and attack those dealsIf you're targeting quantity, then maybe you need to have a lot more than 20 contracts at a time to make headway. 

For example this sheet is saying your NOI for year 1 is 52,548 which divided by 700,000 which is your purchase price comes out to 7.5% I have to say without knowing a single thing about this property other than the approximate location 7,000/mo seems high unless this is some kind of huge house you're doing rent by the room. 

Our 2 units have one garage spot each and room for a short car in front of the garage.
