For example, my house I live in is a MFR, just from the spike around this area we gained 15k+ in appreciation just in our house alone, which has some older features and needs some work done to it (My guess 5-7k).

I keep seeing Zestimate charts showing a dramatic spike this year after five to ten years of stability. 

When housing market tanked 08-09, and many people couldn't qualify for a mortgage due to credit issues not DTI, the rental market (IMHO) showed a spike in rental rates. 

It's difficult to predict what it will be like here in the coming years, but CT is heavily tax burdened, congested and with GE leaving and now Bristol Myers on their heels it's not looking great for property values moving upwards.

Urban density in Seattle-Bellevue-Redmond will continue to spike.

Were these mixed use buildings or did they attract higher heeled tenants to your Condo's location etc?

I know that is not correct but can't help to notice that most guests on BP and other podcasts got their start in 09, 10, 11, 12 time-frames and makes me wonder I may have missed a really good spike but I know there is still plenty of houses out there that are good deals.  

If you are aggressive or confrontational they will dig their heels in and make things as difficult as possible for you.  

If you find that the market rents are that much higher, understand that you will definitely have a spike in turnover if you boost them up that quickly.

However, I know that most of middle america is FUBAR financially, with little to no savings, credit card debt has spiked, and real wages are flat.
