When raising money for apartments,How much would you guys factor in when raising funds to set aside per door?

After reading about the requirements for earning this license, I'm still a little confused about the requirement to be sponsored by a licensed designated broker.If I am working alone, not joining a firm, does that mean I need to form a legal entity and then file to endorse myself as the firm's designated broker?

One difference that factors in is the Term length and what happens if the project finishes sooner. 

As the area improves I believe proximity to the lake for recreational purposes and proximity to the train to downtown will be a key factor for people moving into the area. 

There is a course that I am thinking to enroll in, for earning a designation for residential management.

Designer and GC will be hitting the ground running on a 4 to 6 week flip.

Occasional PMs will not notify owners of a new lease signed, but that never should have happened when the property was for sale, as rental income is a huge factor when purchasing a property. 

I also like the idea of a coin changer when the coins are moving from the coin changer directly back into the bucket they came out ofEPA and waste water may be a factor. 

Do I need to designate one as the "Primary" tenant who will be paying rent?

I would try and get a multi-unit property, although I'm not a US investor so correct me if I'm wrong, but by leveraging it as a 20% down payment, you're able to get a 4 or 5 unit property, which, with the right property, could be a cash flow BEAST, but I would be sure to factor in everything conservatively and definitely keep property management in mind.
