A lot of it has to do with location and time.If they are local owners looking at 1-2 LTR properties, I'll assist with identifying cash flowing/near cash flowing properties, assist them in the purchase as their buyers agent and assist with tenant procurement, listing, etc. but they can typically handle day to day management from there.Furnished properties, whether that be MTR or STR, are a lot more involved, as I'm sure you're aware of!

Hopefully things continue to progress, and you come out on top with a huge equity position/high cash flow when it's all completed. 

Your cash flow is positive on paper, but how will that look in reality?

Property values continue to grow in value, and you can actually live off the rental income.I think it's best to hav all properties paid off by retirement age, since that's when you are going to rely on cash flow for your living expenses.

Roof lines, window styles, and masonry/siding all play into this natural flow, and the biggest mistake you can make when designing your flips is not following the flow that is already present!

We are thinking about furnishing one of the Racine duplexes and listing it as a MTR to maximize our investment and get a higher cash flow. 

I haven't done any deals yet, I've just started searching for a cash-flowing 2-4plex in the last couple months but I'm still about 6 months from being able to afford a 20% down payment with no cash reserves left for maintenance.Aquaculture is an interesting suggestion!

You will make more money on appreciation when you sell your property than you likely will from the monthly cash flow.  

Yes 6 unit preferably with cash  flow open to anywhere  

It's a decent tool, but as Greg mentioned, I'd definitely plan for a worst case scenario and make sure it cash flows at the highest interest rate juuuust in case.
