This is a business decision and should be a part of your business plan for your property. If you are looking for the quality control that comes from having a particular issue taken care of by a professional, then you should hire and pay for the service.
Most tenants will say that they “enjoy landscaping” or will “be happy to take care of pool maintenance” in order to help “save money”. The questions are – will they actually do it and are you actually saving money when all is said and done? Ultimately, there is no one right answer to these questions – it depends.
As stated before, this is a business decision you must make for business reasons. In most cases, we will be able to refer you to competent tradesmen if you need a referral.
