Would a private money source fund a down payment on a buy and hold property?

I need funds for a flip or a quick cash out finance to get extra funds to throw down on my next move. 

My wife and I  have a decent income, i'm a firefighter and she is a cosmetologist and we had been saving money for a while and had been keeping it in mutual funds.

In the unconventional lending world there is no specific period you are required to wait to be able to refinance based on actual appraised value, which means you may be able to refinance and cash out your original down payment funds and potential lever equity immediately following rehab completion and tenant placed.  

As long as this is the only hair on your file to purchase the primary residence a bank should fund your deal.  

From there, I would have to find different funds to start investing with.

When I first started, I thought finding the deals would be the easy part for me and  finding funding would be the hard part, especially because I am only 21 years old.

Is your funding lined up?

I am in the process of working on what I believe can be a potential great deal in Colorado, Wyoming area, but I personally do not have the funding.

My plans will be to turn my properties over to my children, they also invest in rentals, and have them pay me a monthly income or sell and invest in a guaranteed income fund.
