I take care of all the potential problems as soon as I purchase to reduce unexpected maintenance expense in the future.  

The higher ratio is the added management and maintenance labor.

Thus, making it less attractive since the equity interest in the property is reduced.

The following was found in a google search:When septic systems are properly designed, constructed, and maintained, they effectively reduce or eliminate most human health or environmental threats posed by pollutants in household wastewater.

That doesn't make it a bad deal but it will reduce your rate of return.

This can also look very good but is more labor intensive. 

The median home price is around $275-280k, but materials and labor for rehabs are much higher than "normal" (a good price on a shower install is $4,500-5,000 and it can cost up to $1,000 for a simple window install).I kind of feel like if I'm going to raise the money to buy the property in the first place and go to the trouble of taking title, I might as well just do the whole project.

This has greatly reduced my workload and I don’t think I am missing anyone since the #1 question they ask is if the rental is still available since there are so many stale listings out there.

These numbers are high because I provided nearly all of the labor and they were both bought at auction and seriously under valued.My pro-forma going forward is build on a projected 23% ROI with which I will be very satisfied.
