I loved it but have seen the writing on the wall over the years and divested last year while things were still hot.

Right now my primary business is not doing so hot and I am considering closing the doors in order to seek out a regular job - that way I can bank more money for my long term pursuits.

Cobbs Creek and Sharswood are particularly hot right now from spillover. 6abc News just had a great article about how hot the market is right now, selling faster this past July than they ever have. 

If a guest tries to over stay their welcome or is doing something stupid like blasting music from the hot tub at 3am.... you call the cops and have them removed.

Why yes it's got 12 neighbors that will be watching you smoke pot in the hot tub." 

San Diego is a long play and utilizing the VA loan to pick up a property you can truly enjoy AND house hack for less than the monthly of a small apartment is pretty incredible.

Hot water must be functional.Pools must be functional and clear.

Great area and hot market (still despite everything)  there are only 6 homes for sale in my school district. 

That's incredibly assumptive on your part.That said, IF there is a tenant on a property, everyone, everywhere, must follow the law to have them removed legally if they are not abiding by the terms of the lease.

I just want to know how to analyze like how to find out if the demand is high, how do you know if homes are selling fast, how to find out if demand for property in any area rising or falling or how to find out if a neighbourhood is hot or not, I've discussed with a lot of people and they recommend me to use city-data.com which is an excellent website to know about the market but even in that website I don't know what to look for like if the population is 20000 in a city is it good or not or what it should be or what should I type in google to know about a specific market or place?
