(I guess they maintenance the well system and provide salt, etc.) 

Although I only do inspections every six months, no judge would prohibit routine maintenance on a rental. 

Their unit is well maintained, and they currently do cleaning and yard maintenance on the side for other properties.  

@Fred Dray My Current situation is we are a property investment company managing it's own portfolio.We outsource most maintenance jobs to individuals.The management arm has been overlooked by me and the Managing Director when he is available.However my big weakness is that as the company is growing bigger I need to build a strong team and I would like to digitize my management(been mostly old school) so as to provide concise reports for company management.Therefore, I have no idea how to go about it as I've been mostly conducting things myself over the years.Please assist on how to go about this...

A-properties are the most recently constructed units, those that contain top amenities, require low maintenance, and are inhabited by young white-collar workers.

All properties require maintenance, you'll never get away from that, but BIG expenses are (mostly) avoidable in the near future if you buy right.

That may be fine for a homeowner deferring big expenses because they are in the house and tolerant of that choice, but tenants in properties with continuous maintenance calls and poor fixes tend not to remain in place. 

I would use these figures as a starting point and make adjustments based on your area:vacancy - 5%-10%General Maintenance - 5%Cap Ex - 5%?

There will be other costs from the PM if there are maintenance calls and other expenses for the property.Here is what I look for in a PM:CommunicationThe PM should be able to return your call/text/email within the same day, or at the latest, within 24 hours.

You're buying cash flow, very little potential for appreciation, and high maintenance tenants.
