There is always going to be something @Thomas O'Donnell, some fear of now vs later because for every player out on the field making the actions to score the TD's, there is 10,000 sitting in the stands watching yelling out what those players "should" be doing, and guess how many points they score from those seats.... 

The three main things that stand out to me is understanding your finances.

Run owner reports.After testing a few apps, one of them should stand out for you.

In this situation assuming the father was in good standing and especially if they owned property this is who I would pursue since I would have the best chance of collecting and it can be up to him to collect from the deadbeat friends.  

Good news is the house has never flooded in the over 100 yrs it’s been standing.

It's hard to stand out.There are some owner-occupied segments with people who share motivating factors for selling their home.Seniors with Long-time Ownership: often ready to downsize or transition to assistance.Homeowners with Low Financial Stability Scores (FSS): Struggling financially and likely ready to cash in on their asset.In addition, both these markets have probably fallen behind on maintenance and remodeling so you have room to come in and make your mark.

From an owner stand point a central laundry area is always best because possible water/maintenance issues are centralized. 

There are some that do gear towards investors on a national level. 

Also, I realize the original post is kind of old.To reiterate something many other people have said: when you think about painting a room, you see yourself standing there with a brush or roller, putting the new paint on. 

As a wholesaler, especially if you are going to be good at it, you need to do much of the same sorts of tasks as actual investors but what you stand to gain isn’t nearly as significant.
