@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.

When we are blessed with rIches and the ability to do manage it and multiply it we should take hold of that and make good use of our talents and gifts !

Know your market.B) Gross Rent Multiplier (GRM): divide the selling price (retail) or value of a property by the subject's property's gross rents.

Once you have about 25k you’re ready to invest in real estate and multiply.

I see buy and hold real estate as way to buy free time and time is a fixed amount in this life and can’t be earned or multiplied no matter who you are .

Work ethic is the multiplier of the investment you've made in yourself. 

You won't need definions of cash flow, P&L, IRR etc........you'll add, multiply numbers in your head and know pretty accurate if it's too much risk for you to take.If you're afraid of a dog, it's irrational.

3x gross rent multiplier in CA is either a steal or a disaster.20 years ago, when I was in Palm Springs fairly regularly, Desert Hot Springs was where retirees lived cheaply.

This is the other side of things that I don't think you are fully considering ... trying to dance into and out of properties and markets via 1031 to try to time the market cycles is an equally ill-advised strategy, as moving to new markets where you have little experience and boots on the ground is just as likely to net you a loss as it is to multiply your assets to 1031 back into the cyclical market after it crashes (but not as low as last trough).

Earn it, keep it, multiply it.
