Whether the lender decides to do anything, and exactly what they decide to do depends on the lenders particular strategy, target ROI, risk tolerance, current interest rates, interest rate of subject mortgage loan, etc. 

My worry about per snowfall or per hr is dependability.

Depending on the lender (bank or alt. lender) you have to look at origination fees....points, doc prep, interest rate, frequency draws are allowed/min. draw amount allowed per request, interest payments vs. interest reserve & whether interest reserve is capitalized to fully understand the true cash requirements.

Depending on the types of roles, I may be able to get you some resources.Good luck! 

It will probably depend on your experience and connections with lenders.

@Andreas Mathews admirable, but make sure you do some research so you understand what a PM can make.Starting your own PMC business will require 75-150 doors to make a decent living, depending on gross rents and your fee structre.Working for a SFR PMC as a PM, will require a RE license and you usually get paid a percentage of the gross rents the portfolio of owners/properties you manage generates.

It depends on where you want to live, income, personality, and other factors.You could buy a large home and rent out the individual rooms to cover expenses, but this comes with problems.

Another one is when you start to feel a little weight off your shoulders because you don't depend entirely on your boss.

Alexander,It depends and varies hugely.

The success rate is below 30% so it is always do some arrangements with the tenant or move on depending on the case.
