The way I do business is I genuinely try to help people, ethics carry a lot of weight in my solutions, so not taking advantage of anybody, all involved parties will know what's what at all times. 

With SEO you put in a lot of the work in the beginning, and then you can pretty much let go and as long as your SEO is strong like my Kung Fu very little maintenance or upkeep is required.I do believe you need to continue marketing your business, not just leads.

Any thoughts on how much weight should be put into sales comps and listings versus income analysis as well as how to reconcile the significant differences in sales and listing figures?

@Wesin NurThe 1% rule is just a general rule.with all things being equal, good neighborhoods will have a lower % than areas with a bad neighborhood.Good neighborhoods normally require less upkeep and may survive by collecting less than the 1%You also want to determine what the costs normally are for items such as real estate taxes and insurance.If you are in an area with a high property tax / insurance, it will likely be harder for you to cash flow at less than 1%.

You'll also want to ensure you have a good property manager to look after the upkeep of the property if you are not there to notice anything deteriorating or which may need attention.This article goes into a lot of the considerations about whether to form an LLC or not: https://www.mmpph.com/wp-content/uploads/2019/04/May-2019-newsletter.pdfCreating an LLC in California would cost you a minimum tax of $800 every year.

Lot value is not really a factor I've heard talked about much, so I am not sure how much weight that should have in my decision.

There are a couple of quad's in neighboring cities that have the slightly above average crime rate, and chances are would need some more frequent upkeep than the condo.

Only comment is that it seems more relevant if weighted for population. - What was your source for top three GDP?

@Megan Greathouse I grew up on a farm in NE but am familiar with the cost and the upkeep. 

You have to understand that these people do not need to move so you have to find out the pain points which is often upkeep, maintenance, and too much space.
