$80,000 (ARV) - $50,000 (sale price) - $15,000 (repairs) = $15,000 residual. 

It was a whirlwind of a journey, and we were thrilled to see the fruits of our labor with the residual monthly income generated by our rental properties.But as we continued to acquire more and more properties, we found ourselves struggling to keep up with the accounting and office management side of things.

On the other side, wholesalers spend a lot of money advertising to distressed homeowners (cold calling, texting, postcards ppc...) but only a small percentage of the leads coming in are going to fit the wholesale model (less than 10%), instead of throwing the residual 90% away the wholesaler can work out a referral agreement with an agent to recoup some of these lost marketing dollars. 

@Jay Miller Jay send me a DM and I’ll send an excel spreadsheet to you that calculates the hard cost based on local comps.The worksheet runs a residual analysis by deducting everything from the sales price for comparable new homes in your market area.

Additionally, walls should also be checked to see if they contain any residue from previous occupants that might be causing an odor.

A HELOC would take any of that residual cash flow and possibly more.

What residual benefits did you receive from it? 

I am starting out with a few single family properties to build some residual income and then will work my way into some multifamily.

Once washed, you need to rinse with clean water to remove and TSP residue ... paint adheres best to a clean surface.You will then want to prime with Zinnsser (my preference) or Kilz.  

Making it is to have enough residual income to live off.
