For instance, she may prefer a house that is not on well and septic but if it meets every other criteria, she would entertain it. 

I am just not sure how others have made that feasible (in the majority of instances, at least).

For instance, do you want to restrict your partner from being able to encumber the properties?

Georgia, for instance, has nothing called a "township." 

For instance, if you want your rent to be $1800 - you say rent is $2000. 

Do successful investors ever pay market value if the numbers still work for them in rare instances (and it was a buy and hold SFR)?

we buy listed non financeable properties all the time.. so does networth or what ever other big wholesale RE brokerage in your area they are right off of MLS.. whats the difference of you bringing a wholesale buyer through the house as opposed to a retail one off of MLS.. answer NO difference.. my thought Is sellers in these instances think they are saving commission but the sales price is lowered to reflect it and many times wholesalers just rip the pants off of sellers leaving them with 10s of thousands less than they could have gotten with a property open to the market not just a wholesaler who has his own best interest at heart not the sellers. 

For instance, I self-managed while living in the property, but found it more difficult once I moved out so I hired a PM and couldn't be happier with the decision.Lastly, I don't think you need to spend over $1m for a 3 / 4 family. 

For instance, my partners and I have discussed marketing for owner financing to people who own out right who might be looking to down size and want a monthly income.

For instances if I need to do an eviction in Cobb County it is typically a pretty quick process without many hurdles.
