Perhaps I am blind, but with all the resources out there, I don't need to pay someone 10% to collect my rent or take phone calls.  

The only winner will be the government collecting the property taxes 

The lender just want to make sure they can collect rent if you default on the loan. 

Break it down in to singular steps and take each step as they were meant to be taken. 4) Network - If I would have never taken the call from the random dude on Facebook, I'd never have started this partnership where I've learned so much and earned so much. 5) Create processes before you need them - I started building processes out for leasing, evictions, rent collection, and other difficult topics before I bought these properties. 

They are just flipping contracts and collecting a commission. 

I've seen the bad side (although that was 2010-12 or so, so I am old and biased) when inspections was a PITA and at least once cost me more in collective 'inspections fees' than the water tank replacement. 

What is the most efficient way to collect rent?

In comparison, you may buy a rental property with $1100 payment, but you are collecting $1700.

It has made more sense for me thus far investing in the outside areas and collecting pretty much the same or close to the same in return for a fraction of the investment.I definitely agree on the financing portion.

Pay attention to the max rent amount you’ll be able to collect.
