I like a minimum of $50 per unit.You can get free quotes for insurance.Taxes are easy to find.Utilities.  

I'd recommend as @Theo Hicks said to stick to a weekly report from your PM and then calls on as needed basis.Before you jump into this investment, ensure that the numbers work and the overall investment makes sense = low vacancy, demand is high, town population is on the rise, jobs are available and accessible, etc.Best of luck!

Again, DO NOT ASSUME FLIP IS EASY AND I CAN DO IT.

One example is having access to the MLS, which is basically Zillow on steroids.

Not to mention all the access and connections that come with being in the industry.  

If you have a Colorado LLC, you can register it in MO, or, you can create a new LLC in MO.Umbrella insurance is really easy, only a phone call to your insurance company.

Managing this rental so far has been easy and it rents fast.Now the SE PDX market seems to be growing at a slower rate than it was couple of years ago and if we don't sell before next year April, I would have to pay capital gain taxes.So my question is - Should I sell this house now and avoid paying capital gain taxes and re-invest the proceeds back when the market hits a downturn or hold on it this house for the long term?

It's easy to fall in love with a property and end up making poor investments so this is an important reminder. 

If you have a great team, life will be easy, but you have to manage your team diligently.

@Adrian Moreno You have two pretty easy options.1) Go to the neighbors and ask if they know the owners and where they are.2) Use a skip tracing service to get the phone number and heirs of the current owner.
