Even a single family builds can vary significantly based on site conditions and required structure/design.

Engaging does not make you money.

In my mind, the reason for doing this would be to have two engaged platforms versus one dominant one.

We built a single family home version of a 2 bed 1 bath with surface parking at cost with no profit all in with land for 175k in newark ohio, a suburb of columbus ohio. when we push that to 3 units and closer to the city for our build to rent model the numbers go way better. a 30k slab for a single family home is 30k, a 30k slab for a triplex is 10k a door. we designed a 2 bed 1 bath design at 668 sq ft and it's very good layout even I would live there, but I would never build anything that small again. there's no economies of scale. you need density and shared lines, resources, shared roof shared slab, shared windows, etc the cost goes way down.

For projects with 150 or fewer units, the city has 60 days for eligibility review and 90 days for final approval, including design review.

Not to mention we have grown our PM staff by almost 50% to help better support our growth and overall management.We are currently building out 5,000 lots ion Florida If you would like a free copy of my best selling book "Passive Income Playbook: How To Leverage Build to Rent Real Estate to Buy Back Your Time And Have a Legendary Family Life"  just let us know and we will send you a copy thanks Brandon  owned by a Japanese company, the floorplans are pretty poorly designed and larger than build to rent should be. the 4 plex they have is a higher price per door than th national average and needs to be modified. horrible designs.
