Here's how I do it.First, eEveryone does this differently because every investor comes from a different financial situation and has different goals and risk tolerance.

If you have some risk tolerance, I would look into Detroit.

I have zero tolerance for people being pushy and i will push back when need be. 

I went with the 10 locked at 6% because of my experience and risk tolerance.

Whether you should do so depends on your risk tolerance. 

Keep it short etc. or emails people are a little more tolerant ?

Consider whether you have the expertise or willingness to manage contractors, navigate construction challenges, and handle any unexpected issues that may arise.Risk Tolerance: Assess your risk tolerance as a first-time investor.

Everyone has to determine their own risk tolerance, so all feedback should be taken with your own lens of risk tolerance.

There's lots of great information on the forums about each of these reserves and how to arrive at numbers based on risk tolerance and the property itself, but my point is that you want to be sure to be setting aside some of the rent every month for these as well as to pay the mortgage.  

Depends on your risk tolerance.
