@Jimmy Suszynski This is a very specialized subject.

I don't have any contacts in SF or else I'd PM them to you, but if I were in your situation I would look through Google and Yelp for someone local that specializes in that area.

Follow those who've gone before.Find experts specialized around that niche.Partner with team members in areas you are not good at or don't want to do.2-3 quotes instead of 1, will save you on renovations.Always be conservative in numbers and timelines.Have reserves.Set aside reserves for each property.Buy for cashflow.Learn from your mistakes, create processes so you don't repeat them.Network to grow.Rinse & Repeat.

The first property is always special!! 

Should I reinvent my practice as an accountant who specializes in real estate tax and accounting? 

I’d like to connect and partner with a real estate agent that specializes in rental properties, a CPA that specializes in stock market and rental investing tax codes, and anyone else that loves investing, financial independence, and early retirement (FI/RE). 

Do you guys have any recommendation on good local real estate agents who specialize in "househacking" and can advise me on this? 

Plus there are all the special regulations that go along with STRs.....Are you sure you'll be comfortable having strangers going in and out of your personal residence at all hours....?

My partners and I are licensed agents specializing in commercial real estate.

I will be trying to hire a GC who specializes in this type of building to handle the whole project.
