The goal should always to be playing with "house money" and stacking chips indefinitely.That is great that SF's projections are $6k/month on 10 homes.

projects we looked at were in Oregon and if your doing actual MH and your doing a larger project like 100 to 200 units it can take a few years to many years to fill them  and you usually need a mH dealer on site to sell them  etc etc.

Aside from renovation costs, you'll want to consider things like inspection fees, closing costs, insurance, and any unexpected repairs or permits.

A lot less cheaper and will command the same rental rate if purchasing and renovating is an option for you.  

I think you may have very well narrowed down my strategy choices down to one of three; the BRRRR method (although this might be too much to start with for a newbie), the live-in flip that you mentioned (probably the most practical as I've been part of many different projects in the construction industry), and a combination of house-hacking/live-in flip (probably the most rewarding with a potential to swap between units as I finish one in order to bring better rental income).

While it may come at a higher cost, for a project involving plumbing, boiler conversion, and termite treatment, my strong recommendation is to opt for a reputable general contractor.

For part of my graduation project for senior year, I have to partner with a business and provide a service to them that will in turn grow their company.

And unfortunately I’m in the middle of a big project and a refinance and didn’t have the funds to make an offer on the property.

Use a "primary residence" renovation loan (Homestyle, 203K, ChoiceRenovation, VA or USDA) and buy a fixer upper.

Living in the home for a couple years before selling could also provide some tax benefits.If you decide to sell the land with just a foundation, it may be more challenging to find a buyer willing to take on the project of building a home from scratch.
