I've thought about this same thing and I've kicked around some ways to apply the Velocity Banking concepts to real estate investing. 

One is a personal finance concept.

Start with the potential net income to determine the value and work backwards from there subtracting development costs, building costs, commissions and interest expense.If the project looks feasible from a financial standpoint the next step is to check with the city or county planning and zoning department to get an idea if your concept will work, if you can build what you would like to build and what is required for all approvals including site plan, building permits, proffers, water/sewer tap fees, bonding requirements, inspections, setbacks, lot coverages, parking requirements, height restrictions, C/O process and time frame for all approvals.You also need to check with the utility companies and get an idea of availability and cost estimates from them for water, sewer, power, gas, cable, installation and connection requirements, tap fees, hookup charges, transformer location and relocation, power line and power pole relocation issues.

Applying that overarching concept (of taking action when seeing an opportunity) has the power to compound your success tremendously in nearly every aspect of your life.

@Hai Loc I've seen a few proformas for some opportunities in Toronto recently but I haven't invested and am not too familiar with the concept.

@Christine LangI really had no concrete conception of money as power until the country of Greece went under in 2010, and even then the lesson wasn't really rammed home until 2015.Imagine you lived in a cash economy where very few transactions were completed using credit cards, bank cards, or personal checks.

However, I think you want to start with some SELF-STUDY so that you are able to grasp pretty straightforward concepts. 

The whole concept here is that you BUY and REHAB below/at the maximum "Loan to Value" of your REFINANCE step. 

Also most won't call it the BRRRR specifically but it's the same concept.

As I have been building out my financial models, and comparing them to the BP calculator and other resources I have found online, I'm stuck on a concept that I wanted to ask here to validate whether I am thinking about this correctly.
