Thinking long term, after I move out I would like to rent them out separately to maximize cash flow.

On a separate note, I would seriously consider disposing of those SFRs and using a 1031 exchange to get into this or another 5+ MRF.

My plan has been to use the cash investors that I've already networked with to use their POF to get a deal under contract - either under my name then assigning the contract or under their name with a separate legal agreement to get my fee.Thanks for your time, I look forward to your advice!

I try to keep all those separate and don't need my business debt reporting to my personal credit. 

Many MH investors separate their investments into two components A) the real estate and B) the wheel estate. 

QBO Plus has class tracking, which is what you need to be able to track and separate by property.

It is just like any other loan except the lender is the seller.The two concepts are separate, but can be combined.An example of a sub2 without owner finance: An investor buys a house sub2, keeps the existing loan in place, and uses the house as a rental.An example of owner finance without sub2: An investor owns a home outright.

Either a split level style or separate in law suite downstairs. 

My second question is would it be easier to rent my bedrooms as a pair, or each one separately.

It’s probably best to keep business and family separate - the initial contractor was distant, distant family2.
