Questions - Best type of loan on 3 properties free & clear

[Greg Grant]

So I own two properties currently (free and clear) and may be picking up a third soon, which I plan on paying for in full at closing.

One of these properties I currently own is our house, the second is a warehouse (w/ 2 bays as a rental) and the very likely third property will also be a 2 bay warehouse rental.

My wife and I would like to move into a new home somewhat soon, but this potential property came up all of a sudden and I can't see a reason to turn it down.

So hypothetically, let's say we get this third property in a month and in 8 months we decide to go for the new home.  What would be the best method of a loan in order to secure the down payment for the new home?  Should I do a Line of Credit on one of the warehouses?

For this scenario, let's say the home we currently live in is worth $240k, the current warehouse rental is worth $350k, and the upcoming warehouse will be worth $300k.

The new home price would be somewhere around $400k so I would like to have around $100k to use towards a deposit, and then once we get in, then we sell our current home and take that $240k and put it towards the new home (probably as a refinance to get the best rate/payment).

I currently don't have a loan on the current warehouse mainly because I wasn't sure of any loan programs that I would qualify for at the time I bought it.  I do have a 785 credit score, so I'm not worried about that.  My issue is I am a self employed person and not sure if they still have no income verification loans (since the mortgage bubble), like they did when I bought my current home.

And I'm not very keen on the idea of buying this upcoming property with a loan when I have the funds available to purchase it outright, why pay the interest on a loan I don't really need.  Is that the wrong way to think of things?
