I bought my rental in the summer of 2014, and it has given me a steady stream of revenue ever since.

The newer valves are pressure-regulated, so if a toilet is flushed (or another shower is turned on), the pressure may drop a bit, but the temperature shouldn't change much.Maybe it's easier/cheaper to upgrade the shower valves than changing the water heater setup?

What is the best way for steady income in real estate?

You can loop them into separate thermostats so you can be pretty specific about individual rooms and temperature without adding a ton of cost so long as you don't go overboard.

Do you roll the dice on your gut to do better quicker, or do you take the slow and steady with the above numbers and dig out slowly to achieve what you want and possibly miss the potentially better deal?

During the down turn the $1000 rents or below will stay rock steady or go slightly up as demand will increase in that economic level.  

They like the steady stream of income, but are getting too old and tired to deal with tenants and maintenance.  

The population looks like it has had a slight but steady decline over the years.

I advocate a slow and steady approach to scaling up your social, based on real-life results.

I found that I have a low risk tolerance, and I "need" steady income for health insurance and to make sure that the mortgage gets paid.
