And all of this is a SWAG - Sceintific, Wild Assed Guess.  

Underwriters are likely to rate differently depending on how close it is to the house, because of wild-fire dangers.

By using the 1031 you'll pay no tax, get into real cash flow and away from a Mayberry gone wild.

Let's just get wild and say it'll cost 2k to rearrange a kitchen (again, I would never pay that), but we're still at 15k. 

In my opinion, absolutely.The thing that's a bit of a wild card is historically low interest rates that actually mutes some of the effect of housing gains.

What's difficult about valuing notes is that it's an asset class that can have wildly different opinions of value by those unfamiliar with the complex variables of a note created via seller financing.

I learned to talk with the park manager ahead of time (this one ended up being wildly unethical.

If there is no second financing, ask the title company for an "All Inclusive Deed" I'm not familiar with deeds used in Cali, you have some wild twists out there, but the seller needs to have a security interest filed. :) 

Hopefully, that wild ride taught you everything you didn't want to know about real estate, and everything will be smooth sailing from here on out.  

The individual rate living below the poverty level is 36.4%; the family rate is 31.3%.[50]Urban decay[edit]This map shows vacancy rates of housing units in Wayne County, Michigan, and also in the city of Detroit.Dance floor of the Vanity Ballroom Building in 2010.The Film Exchange Building in 2012.Detroit has been described by some as a ghost town.[51][52] Parts of the city are so abandoned they have been described as looking like farmland, urban prairie, or even completely wild.[48]A significant percentage of housing parcels in the city are vacant, with abandoned lots making up more than half of total residential lots in many large portions of the city.[53] With at least 70,000 abandoned buildings, 31,000 empty houses, and 90,000 vacant lots, Detroit has become notorious for its urban blight.[51][54]In 2010 Mayor Bing put forth a plan to bulldoze one fourth of the city.[55] The plan was to concentrate Detroit's remaining population into certain areas to improve the delivery of essential city services, which the city has had significant difficulty providing (policing, fire protection, trash removal, snow removal, lighting, etc.).[51] In February 2013 the Detroit Free Press reported the Mayor's plan to accelerate the program.[56] The project has hopes "for federal funding to replicate it [the bulldozing plan] across the city to tackle Detroit’s problems with tens of thousands of abandoned and blighted homes and buildings."
