As someone in the preservation phase of their financial journey all I said was any less than a 7% return I'll invest in things that require less work. 

Then, control costs to preserve your wealth.That is, you can't preserve wealth you haven't created yet.Every hour you spend unclogging toilets, mowing lawns, painting, ... is time NOT spent building your business.Do you want to be a business person or a groundskeeper?

The more I look at the wholesaling or Flip part of the business it looks like if an investor doesn't obtain a property at 50% ARV, then they don't have enough headroom to preserve an above average profit margin. 

Contract the work out and expand faster at the cost of carrying greater debt OR Do the work yourselves, expand more slowly but preserve your capital so that when you do expand, you carry less (or no) debt into the next deal.
