-no vacancies-no repairs-no maintenance/capex? 

You could frame it as a way for them to get all the cash up front and not have to worry about maintenance or expenses on the property anymore.

More space = more maintenance. 

So, if you can budget for maintenance and maintain adequate reserves, you will be much better off in the long run skipping purchased warranties. 

I did not consider it "cashflow" as i just saved it for capex/maintenance.

How often should I come up to do a routine inspection?

Your credit is a test - when you have 200 properties that's 200 property tax bills, 200 insurance bills, 200 maintenance bills, bills, and bills and bills and bills. 

If these are new builds, there is probably less maintenance, less need for large CapEx reserves right now, and if the rent is covering the mortgage, you're in a great spot.

If you were having trouble with maintenance, tenants, evictions, crime, etc why would you think the property manager wouldnt as well?

I had 125% inputted for Repairs and maintenance, 75% for Vacancy and 125% for Capital Expenditures 😅 just switched them all to regular percentages and it's now showing negative $1,030 cash flow with $3,530/mo expenses.
