It is counter-intuitive, but more expensive homes is much easier.

I don't know if it's counter intuitive or not but your best intermediaries are going to be in the cluster of the middle range of fees.  

These include accidents (I recently had 2 units destroyed by fire), natural disasters (I have had two units each hit by 2 hurricanes), property management turn over (they sell or stop being as good, I have experienced both), or turn over of team (I am turning over at handyman and I suspect plumber), or just wear n tear of property (slab leak in poor location, sewer pipes rotted out (one unit this month), roof, foundation issue, etc.).  

The price started at 120k and I counter-offered 90k to which the seller was going to accept.

You can look at a mobile home and see it as an easy rental with new carpet, trim and some paint but there are other bigger uglier expenses that can come up.Roof Replacement, soft floors (water damage) in kitchens and bathrooms- most floors are particle board, exterior door replacement (special order), underbelly insulation falling, bad hot water tanks with rotten floor underneath (real joy), bad windows (water again), bad bloated siding (water), water damaged base frame around perimeter of home, cracked tubs (special orders) and frozen pipes (Good luck finding a plumber to come work on a mobile home- they do not exist). 

The kitchen counter laminate was also very dated looking. 

I started my OOS HML  career in Detroit and that was 2002 and WOW coming from our area what an education I got.. my clients that were doing turnkey at the time and all the buyers were out of state ( basically LA based) the local on the ground operator was very good he had all sorts of tricks to try to keep the houses safe.. the one i really liked was painting the copper pipes grey so thieves would not steal them..

Some things come up that might be hidden which could be piping that needs to be changed out under a raised foundation or something like that for example. 

When you have a minor leak beneath a bathroom, it's most likely from the drain pipes, which is why the water only leaks when someone uses the bathroom.

@Aaron B. yes those numbers are a pipe dream as well.. but then you get on BP with a pod cast and there ya go... its one reason I have not done a pod cast in 3 years...
