Avoid 20% Down payment on investment property

[Max H.]

I was hoping someone on BP could provide some guidance for me. 

I purchased a foreclosure 18 months ago that needed repairs. I did the repairs and am now living in the house. I noticed prices in the neighborhood starting to go down so I decided to do a HELOC. I closed on that last week and I want to put most of that money into a down payment on another house.

I'm trying to avoid putting 20% down but since the next house would be considered a second home I'm not sure this is possible. Help is greatly appreciated!!
