You are missing my point on taxes.Scenario 1:  Your partner buys the house at the same time you put your cash in.  

The biggest question you need to ask yourself is if you are doing this to afford a property you otherwise couldn’t afford or to save money period, that will lead to very different conclusions about where/if to buy. 

Not if you buy 10 at just the right time to hit their sales target.

To buy or not in Portland!!!!  

I'll buy the fuel if you'll take me up!

So, if you buy an older home it's typically much cheaper, since you're not paying much for the structure. 

I have been wanting to buy this piece of land for years and it has recently become available.

I still have enough room with my VA entitlement for a buy and hold in a couple of years, so I'd rather save it for later!

I will add that to your question of 10% or 20%, you need to ask yourself whether you need the cashflow or not. 10% down would leave some money with which to buy more properties.

If you sell for a net sales price of $1 mil and buy for a net purchase price of $700K you will owe tax on the difference of $300K.BP may have a capital gains calculator you can use.
