One: go find a really good contract attorney that understands seller financing, wraparound mortgages, subject to existing financing, creating notes that can be sold in the marketplace (note brokers), the ability to repay rule from the CFPB, the safe act, Dodd Frank, TILA, RESPA, etc.

I'm leaning towards SFH for the ability to buy and sell quickly as well.I will indeed be able to get 30 year financing and you bring up a good point with the 10 max loans. 

I understand there are many factors to determine ability to rent out and value. 

I like the idea of an LLC, however I am afraid it will restrict our ability to get loans at decent rates, if at all.

When I had no track record and little experience, the only "private investors" I could find were family, and the only reason they invested with me at the time was I had a successful track record in businesses other than real estate.Once you have demonstrated the ability to make profits and give people / banks back more money than they gave you in a short amount of time it's pretty easy to bring new investors into the mix.

That's just life, but  with no emergency fund at their disposal their ability to pay rent on time always seems to suffer. 

A cash buyer has the ability to use their own funds to close, they have cash to close.

I prefer to rely on my ability to screen for good tenants than on the government's ability to continue to pay me.  

-If the interest rate is fixed, what is the max interest rate, assuming the buyer has the ability to pay?

Not an easy task as over the years, I have developed an ability to borrow private funds or do JV deals so I had never taken out a hard money loan and with all the lenders in this field, options are almost unlimited for a person at my level.As to the wholesaler, for once, I found a deal that hit my desk where true value was added.
