Leonard;
You don't necessarily have to find all the money. You should probably have 10% to 20% of the money on hand, because you will need some cash for closing expenses. But there are many ways to buy houses without a ton of cash.
FIrst choice of funding for me is the current owner. I have bought many houses with owner financing of one variety or another. Whether it is a wrap, assumption, straight owner finance or other creative method, owner financing does not require that you have a lot of cash. Not every house can be bought with owner financing, so it may limit your choices. But it may also open up choices you would not otherwise have because you did not have cash to buy your dream house yet.
Another choice of funding is: spend less on a house than you planned! The less you spend, the less you finance! Instead of buying the maximum house you can afford, buy the minimum house you can stand. Fix it up, sell at a profit, and use the profit to trade up.
Of course you can also go the route of prequalifying for a loan. Many people do. You can also get to know private lenders in your area. If you are buying as an investment, you can find a private lender who will lend to you or who will partner with you for your first property. Private lenders will not typically finance your homestead, but maybe you need to work up to that milestone.
Until you find the property, you don't know how much money you need. You also won't be as motivated to actually find the cash. So from my point of view: find the property, then the money.
