Financing based on lender's equity in the property is much preferred. 

Depending on your state, you might consider a Land Trust. 

One property did at least provide reasons why they were selling the property (I had to ask, because the property's cash flow is insane based on their description). 

I made the decision based on the slow response time, amount of rental properties holton wise owns themselves, cost, and being given bad information (I still am trying to track down the prorated rent from October when I closed).

I bought a manufactured house and the land for 60k.

You just need to speak with relationship based local banks who will lend on apartment buildings, mixed use, local commercial deals, etc.

No, it only applies to properties held for production of income (rentals) or for appreciation (land) or both.

I am also going to required annual increases in rent based on the CPI index, among a few other things.Does anyone have experience with this?

So who knows how much some of the land value could increase over that time.

Based on what metrics?
