I will link a couple articles and will still swing back for more questions, but I mainly wanted to help the OP recognize that through the use of a Land Trust the Due on Sales Clause can be avoided.https://www.biggerpockets.com/renewsblog/the-traditional-llc-vs-the-series-llc-which-is-better-for-real-estate-investors/https://www.biggerpockets.com/renewsblog/2016/07/17/real-estate-asset-protection/

If you are buying and holding my suggestion is to do a traditional refinance so you can have a fixed payment. 

Many of which is already found in traditional rental agreements.

Buy and hold MFH is my strategy.After a few months I found a property which would meet my requirement of 15% CCR with traditional financing.

Paying a buyer's agent 3% is far more palatable to me than the traditional alternative.

Traditionally a mentor is not a paid position and good investors  dont sell good leads. 

Traditional banks with Fannie / Freddie / conventional loan types will sometimes push back on the LLC issue, but there is a BIG world of funding and lending for investors outside of that box.  

I don't flip, but from my understanding you would not use a traditional bank to get these loans unless your rehab is over 6 months, you would use a Hard Money Lender.For long term buy and hold I would leverage the duplex and buy more properties, and then I would use the profit from wholesaling and flipping to buy more properties.  

@Chuck Wiggins I've heard of rental loss insurance for property damage, but not for rent (unless of a traditional insurance claim).  

If I was renting to traditional private pay tenants Germantown might not be my area of focus.
