BiggerPockets

This is precisely the mentality that has so many homeowner's in trouble today. The biggest assumption in that theory is that homes will always appreciate in value... The real estate market over the last two years proves otherwise.

Although this is a good idea, do not over leverage yourself.

If you want to control more property you can go after property with less than a 25% down payment. If you make a decent wage and dont have a ton of debt you can get several loans. I would try VA REO's first. These can be had for 5% down. You can also look for property from local banks. In my area, there is a bank that will sell you property with 10% down. So if you were originally going to have to put down 25% for one property, you could now buy two local REO's and one VA REO. You will need cash to fix them though. You will also need a reserve incase of a problem or budget overrun (common on REOs).

Also, try to have the seller or bank wrap the closing cost into the loan or pay for them so you have less out of pocket up front.

After you get those three properties, seek out seller financing or do some options. Good luck, stick around on BP and learn a little, and stay away from Gurus and their boot camps.

In principle, what you say makes sense. However, in the current economy, you will not find a loan for zero down. You should look into subject to purchases or assumptions if this is what you are looking to do.
