This is a game of patience and time is the ultimate wealth multiplier. 

I am looking to writing an aspiring story about my success in real estate and to multiply with great partners! 

Multiply that by the national average commission and you will have average GCI per agent. 

If you want your own office you can do so too, and build your team and make money with your team and empower your team to build their own team so that you multiply your efforts on training your team and sells.

What you go on to describe here is the money-multiplier effect, or "monetary velocity".

Holding Costs are calculated by multiplying your Monthly Holding Costs x Flip Holding PeriodTypical Monthly Holding CostsHere's a list of typical Holding Costs and average amounts that you will likely have on your rehab projects.​Property Taxes - Property taxes will vary depending on your local property tax rates.

If I were to conservatively run an estimate, I’d take the total revenue on airdna and multiply it by .70 to reflect the cleaning fee, maintenance, and a small buffer.

@Mike BecherIt may be difficult to find the calculator that you are looking for.This is because everyone's tax profile is different(some may be in a 0%, 10%, 12%, 22%, etc tax bracket.there are over 50 states and some states have different rules on addbacks of bonus depreciation/section 179 expense.Furthermore, some people's deductibility depends on whether they participate in the activity or don't.I can go on and on...but there is a lot of variables.With that said - you can get a good idea by taking your cashflow(adding back principal payments that were deducted) less depreciation and multiplying it by your marginal tax rate.If your total income is above $100,000. some of the losses may be limited.
