Although I'm not opposed to something a bit more passive than being a landlord again.I always knew my return was low comparatively .. not to mention the many hours of stress, physical labour and tenant management that have gone into the home.

Sure looks like the average increase or decrease for the city is applied to the existing value.  

While it can be done and many do it, it’s not easy, stressful and risky.

I'd say the true passive real estate investment is being a private money lender.If you want to decrease the maintenance on what you have, you could do some major fixes on what you've got, which can push out your headaches for years.

You still have to pay the mortgage out of that which decreases your cash flow, but now if one rental is vacant, the other 4 are still earning money. 

Barring a self-inflicted wound by acting rashly while under stress, there is very little chance that this will cause you to lose the property.
