@Ronnie GalindoIf you can wait another year, look into Internal Revenue Code Section 121 - exclude the gain from sale of your principal residence under certain circumstances.

Again, I have 100% equity in the house.I was asked why I don't get a home equity loan and the reasons are 1) My credit probably shows me to be a "ghost" since I have not had any sort of credit in the last 7-8 years and 2) I have worked for myself for the last decade and my income is usually in cash so, it would be impossible to prove any consistent income.I never would have thought that getting a short term loan under my circumstances could be difficult to put together.

Stanley was fascinated by the different ways women get rich as opposed to the ways that men get rich.He believed that his research into millionaire women allowed him to separate them into two distinct groups, with minimal overlap -- women who got rich because they came from stable households that prepared them to become successful with money, and women from very different, unstable households who got rich in spite of the odds.

Do not under any circumstances enable her.

@Daniel Urban, a commercial property's value is based on how much money it IS generating, not how much it COULD be under ideal circumstances (there are exceptions, of course).If you're serious, I would determine it's value based on the information you have and generate an offer based on that.

However, given that we’re both military and a couple other circumstances, we have a bit more capital than a typical young-20s couple to invest so are also looking to buy a multi family (ideally quad or tri-plex) property that we can do some light rehab on and start cash flowing.
