9) adding multiple ADUs or adding an ADU to a quad looses F/F conventional financing.

You can also partner up as well/have multiple people on the loan for down payment purposes!

I personally like one sponsor who has been through multiple real estate cycles without losing any investor money, puts very large amounts of skin in the game, is conservatively leveraged and has a very good 1031 exchange program.

Let’s be honest, I’ve watched folks who jump into this game as if playing roulette.. firing off offers on duplexes in Phoenix or leaning on some “sure-thing” house hack in Austin without ever sketching out their plan.

Real estate's "gross rent multiplier" is Wall Street's "sales to revenue",  "cap rate" is roughly "P/E ratio".When evaluating markets and investments I tend to start with GRM (or lazily the 1% rule), then attempt to return a cap rate based on assumptions about costs, then I work my way to multiple years of projections (assumptions about inflation, amortization, tax benefits, etc), and if I am partnering with one of my smart friends I have to pull up an IRR (internal rate of return).I also look at regional employment levels, median income to rent ratio in the zip code etc.

You can read a book and multiple books, but unless you are out there doing it (I.e. getting bids and getting contractors to truly get you an exact estimate) you will be far off from the numbers you want and may even lose money on the flip/rehab.The best advice I would suggest in my experience is that you should get into the line of work by either partnering with someone or working with someone on some projects prior to going into a flip on your own.

That way you’ve got some skin in the game, and the tenants will be less likely to protest that the other tenants are using more electricity or gas.

The only time you would see a fee related to maintenance would be a project management fee if multiple trades are required during a property turn.
