Stop in for a cup of coffee

Financing? For you, A VA loan should be the only option you should be looking at.
Right now, there are loans in the sub 3 percent range, 15 year. If the price is not too high, you can pay a loan off in 15 years, saves a ton of interest over a 20 or 30 year deal...IMO, do not take equity out of a home you are living in, for an investment property. Don't risk a family home on a lark, on a "maybe" deal that is an investment property. Who knows if it will get more valuable?
And you should look into forming an LLC. Will protect your family in case a business venture fails...
