Just a thought - have you looked into security window screens?

I did not screen my market at all.

Screening is still vital.

The home sits on a 1 acre mostly-flat, square, and mowed block at the end of the street.

Therefore, you will see the different sides: customer service, maintenance, collections, screening, renewals, leasing, IT, etc. 

Many argue that identifying a flat % based on rent can leave too great a margin for error.

Many people just assume rent will grow at 2-5% per year, but what if it stays flat or drops?

I was wondering what is a good app to post listings, screen tenants, collect payments and all that without having to hire a property manager right away. 

And if you are a good landlord that repairs and replaces things and has well screened, happy tenants that are fulfilling their lease terms- then it will always remain work... but happy work.Now, I am a ghostbuster.

Pricelabs is great and is a flat fee.
