The key benefit to a Dutch repayment schedule is that they are often easier to find, the approval requirements are lenient, they tend to close quickly, and the calculation is very straight forward easy to keep up with.

If you are this close to the border or cost you need to purchase through a corporation or through a bank trust (Fideicomiso - Think of this trust to be similar to an inheritance trust or a living family trust in the US.)At all times you are the legal owner of the property, the best way to see it is as a permit or license that allows you to purchase, use, enjoy, rent, renovate, inherit, etc. a property in this zone.

They just want reassurance they are dealing with someone that can close.

You have two choices - either drill a well, or get an onsite storage tank and have water trucked to it weekly.I think the price for the well is going to be much more than you're thinking, so I would check that out first.

Some would argue in support of a neighborhood in close proximity to downtown Sacramento such as the homes off of Lighthouse Dr, others would want to attract families with elementary school children who prefer homes in Bridgeway Lakes near Bridgeway Island Elementary School due to it's higher Great Schools rating vs.

I would look into some lead sources that you only pay if you close(Opcity etc.). 

Upon initial purchase, most of mine are nowhere close to that.

I found it on Zillow and paid list price, less seller credits for closing costs How did you finance this deal?

If the property owner is a "long time childhood friend", then she may be willing to cut you a deal where she pays for the closing costs and/or she may contribute to any repair/remodeling work that the property may need.Once you move in you could house hack and start saving money so that you can acquire more properties.
