@Rich Bultema - Just from my experience I have not had an appraiser impact the value for an older heater/air conditioner, however, a heater without A/C (as an example) has impacted an appraisal on a single family home.

To their credit they're being pretty transparent about how this went down and they say they've hired a lawyer to take action against the inspection company they hired.  

Is that specifically a central air unit or did the furnace crap out?

If you just hire the cheapest or first PMC you speak with and it turns into a bad experience, please don’t assume ALL PMC’s are bad and start trashing PMC’s in general.

just a couple things:-you can house hack and not deal with tenants directly as @William Collins notes. you just hire a property manager. it will cost more, but that's the trade off.

Join a broker or hire a coach where you can learn how to convert leads.

In my opinion, the more income you have, the higher the allocation should be towards stock / fixed income.As much as you can make real estate passive(Hiring a PM, getting into syndications), there is still a level of work that you need to do.Why spend hours when you already can afford what you can.The extra return isint' worth it.

Also crawlspace air also not that good quality if air leaks through those loose ducts.

This could involve hiring local property managers to handle day-to-day operations.4.

I have been recruiting professionals for a long time, so I know what to look for when hiring someone.
