On the 2nd go around the seller can void the contract.But as a general rule if the contract does not mention they can not void, then they can void the contract once you open the contract back up for negotiations, because now you no longer have a ratified contract, but you are now negotiating again.

For example, if you can prevent the nightmare tenant, you avoid--well-- nightmares (like real ones, where you lose sleep or wake up worried how the eviction will play out or toss and turn wondering if the non-paying tenants are trashing your place; you drift off imagining them doing nefarious things under dim lamps with bunson burners and beakers amid a pile of trash surrounded by half feral pit bulls resting on dirty mattresses)... 

To balance that, most buyers would offer a lower price to raise the returns back up so that this investment’s return is competitive with other investments that don’t have this constraint. 

Additionally, it was an epic moment using the knowledge of an iconic BP figure, like Brandon, to jump start a negotiation back up and ultimately close on a deal.

That you would like to further your education and be able to, when in conversation, back up your claim.

So when they get calls for new jobs with more money yours goes on the back burner.

I should back up a little and say that I have been listening to an older podcast every few days (and every current one) and have read two of Brandon’s books so far).In older episodes, Brandon had been talking about buying a trailer park with “owner financing”.

The back-up plan is to simply flip the property and take the cash out now for the next project.The Project (2 unit Multi-Family):Acquisition/rehabLand Acquisition:     275k (I'd use my cash to buy)Hard Money Loan:  100k (I might use my home equity line at 4% APR over 20)ARV:                           465k (This is my best assumption based on other comps)Refinance:                348,650Cash out:                  26,250Income:Rent:                         1800x2 (This is conservative)Capex/Maint.          300x2Expenses:                400 (water/trash/electric/sewage/insurance)Using these numbers the property looks like it generates a COC return of about 30% per anum (on the 26k outstanding).

If he sells to you with owner financing then you can pay him monthly, a check that he can depend on that is back up by a real asset.  

After the rehab is done in about 6 months, my equity position should be back up to 40%.
