For you to gain enough experience and talent to be able to rival a real GC would take you a decade.This is like when people want to get a RE license to save money doing flips....ain't gonna happenLike @Joel Forsythe said, this is a myth that perpetuates the industry.

Timing the market is like day trading in stocks and runs counter to the benefits and security of real estate over other investments.It goes without saying that current prices and rates need to be factored in to your underwriting.

The owner wants to minimize the capital gains tax he pays so we want to suggest to him to do a master lease to us for "x" amount of time, and we pay his lease fee and hold the rest of the money in this time we will secure a loan to buy using the money we make as part of the down payment.

Looking to connect with more investors who would benefit having all the services they need for rentals under one company. 

Quote from @Gaines Lydell: Great company!!

I find most invest all of their money and energy on formulating complicated entity structures and then obtain insurance because their lenders require it, not necessarily because the borrower/investor values the benefits.

I have been able to find sellers by looking for similar properties to mine and hand write “I want to buy your house” letters, outlining the benefit to investors of seller financing.  

So they want to pay capital gains tax right away instead of letting it appreciate tax free?

If you are not on title, then you are not taking a capital gain when the sale of this home occurs.

It may be easier to claim real estate professional status.Have a conversation with your CPA to discuss the benefits and to see if you qualify.
