Despite becoming a wealthy and successful CEO who could easily afford to hire help, George Romney instilled this same work ethic in his kids by requiring them to mowthelawn, shovel snow, rake leaves, weed the garden, and clean the house.
If you do not have the time, ability or inclination to interview renters, place ads, mowthelawn, repair broken appliances, steam clean carpets between renters, etc. you may want to contract with service providers, such as a property-management company, yard service or housekeeping company to ensure that the property is maintaining its value and that you know what your renters are doing.
These are the people who mow your lawn, flip your burgers and, generally, fill any number of jobs that provide an income that walks the line between the ability to support a family and having insufficient money to keep it all together.
