The purpose of withholding throughout the year is to cover the taxes at the end of the year when you file your return.The amount you have taken out from your paychecks depends on how you completed your W-4.You are calculated as paying 'one tax' based on your income.The tax system we have is progressive meaning the more you earn, the more tax you pay.So it is hard to say what tax rate you should be paying without knowing all your information.Ask your accountant.

Hi RyanYou have a terrific resume, & those skills will come in handy.  50 properties in 4 years is very ambitious, please keep us updated on your progress.  

They approached me about me putting a down payment down on a property that they would live in, and then contribute part of their rent to gain some equity progressively until we shared the property 50/50.

There is a lot of unforeseen issues that will likely drive your cost about your budget and drastically reduce your profit margin/equity in the property.BTW, I like your positive energy to get this done.Goodluck and update us on your progress. 

How  and what are the pricing steps needed to put into progress?

Work in progress.

The points you mention are all largely factors of good ole progress, and that alone.

I think that will help to stimulate progress... 

Having a local bank fund the DP (Currently in progress)Roadblock: I spoke with my bank and the guy told me they might be able to give me a business loan as the DP and I was overjoyed, but over the weekend I remembered they will probably want to see a collective LTV on the property of around 75%-80% including the seller's note.

@John Seilus Post about your progress!
