.: I would highly suggest buying an existing community, it is almost always easier and more profitable unless you know what you're doing. logan the issue on the West coast is parks are treated like investment grade props and sell at a very low cap rate even in this interest rate environment. 

I was just wondering if I would be able to get a solid deal considering my credit score is only 680 (I'm 18) and low amount of capital.

Take one of the vanes to Home Depot, Lowes, Menards or a similar store in your area and they will help you match it.Clean vanes easily with Clorox Wipes.

It pays the taxes, the water and sewer, and the cost to heat the property while leaving some for maintenance.

I've seen them with low fico requirements

I know it is not an optimal rental with how big it is but I am confident that the equity will be increasing quickly along with rent rates given how much money Lennar is pouring into the area and we have low rates. 

But they felt like they had to market a low rate to "keep up with the Joneses".

SMF you could start in the low 200's that are in a better area with cash flow potential.

Nice Chart, The unfortunate part of your chart is that there are many more products out there that don't sell to Home Depot or Lowes for various reasons that I won't discuss here.

Not too low either, you don't want to go with someone who is just focused on price as this is a quality of a not-so-great accountant.
