This is why most unlicensed brokers have to operate in the shadows and try to hide their identity, etc when advertising illegally.

Meaning, the rate will fluctuate and in 10 years they "mature" into something else. 

How much equity, how old the loan is or how mature it is and things of that matter?

I'm guessing the answer to these questions is that the scenario would be identical to refinancing the mortgage as proposed above, as far as the LLC issues are concerned.  

But that number is skewed because surrounding Wanamaker are many vinyl village housing developments which all have pretty much identical rents.

However The property I have in mind is currently listed at 147K the owner owes money to the HOA so they need to sell if I offer a cash offer of 127K and they are willing to go the low the investor would love to buy because an identical property sold for 169K in the same complex.

Even if someone has built the exact same house you want on an identical lot in the same neighborhood, your cost is still going to be highly dependent on lots of things:-  Do you hire a builders or do it yourself?

I own and live in the identical 4 plex right next to this one.Well one of the tenants in the building built a deck in the back yard.

The unit next door is in great shape/move-in ready, and is in escrow for $420k; identical floor plan and space.  

I am a firm believer, it does not take long to have a conversation with someone and find out where there head is...When I screen a tenant, Im looking for an older mature type couple that has their head on straight.
