I worked as a Maintenance Tech for Essex Property Trust at The Highlands at Wynhaven apartment complex in Issaquah Washington for 2.5 years to learn how to tackle the problems that arise with rentals on a large scale, but not really knowing what my goals or vision was.

Although I'm an engineer in hi tech, my most memorable classes growing up were woodshop.

With all that now I’m getting the ac don’t work again so I send out a ac tech I explain to them the the tenants are claiming that the ac isn’t cold enough that the Edison guy that took off the summer saver box off the ac fan told him the ac needs a Freon boost I’m really  now the  Edison guy is a ac tech the ac was running cold now it’s not working .well the ac tech did a leak test ,pressure test and said it was fine  but it looks like it was tampered with he also said if there was a leak there wouldn’t be Freon in the system still so I payed him to fill it up  since there was  few pounds of Freon still in the system he also asked me when was the last time i serviced the ac  I told him about a year ago .he said that long ago if there was a leak  there would be nothing in the system so after paying a few hundred dollars ,now I get another call saying the ac is blowing hot air .so I send the ac guy back  .the same ac guy said looks like it’s been tampered with.so now I decide to pay for home warranty insurance after the second repair and now  the tenants threatened to sue me.for my fist rental this is a bad experience of tenants trying to scam me and the plumber his freind doing fraud.i later called the water company again spoke to the manager this time explained what going on.he said just tell the tenants to call and give a one time to talk about the bill that I don’t have to be on the account so i did they refused again.

I did a recent project where we converted a giant closet into a bedroom and added a window and a normal sized closet into the room. 

There has been a lot of development here in the last few years and a lot of tech jobs coming to the area. 

I am a recent graduate of Georgia Tech, here in Atlanta and I am currently working as a Product Engineer at a biotech company.

The answer to your questions are just a giant "it depends." 

Don't fall down the tech rabbit hole.

I am an old-school tech guy from Silicon Valley.
