Hi- Wife here!
" It's taken a long time to get my credit straight and debts paid down. " This indicates that you may have not have been so responsible with money in the past. She may feel insecure about it still.
"HELOC, turning over traditional 401k to SDIRA" - putting the house and or retirement at risk: more insecurity
"Completely out of debt... Probably a good 5 years off." This indicates you either have a ton of debt or a small income (i'm guessing small income) more insecurity
"we're getting there but by that time it'll more than likely be too late to build the wealth I would like for us" This indicates either ignorance or impatience/immaturity on your part (don't mean it harshly). Any time is a good time for real estate!!- the real estate investor must just adjust their strategy to market reality. She must feel this too.
The best time to invest is when *you* are ready to invest.
So my advice to you, as a wife who, with my husband, went from debt/ low income to good income, no debt and re investments:
1. Be patient with your wife, and yourself. Realize there will always be opportunity. Lay off the real estate talk for a while.
2. Show Don't Tell: Work like a dog to get out of debt. Extra jobs, insane hours, serious budgeting that you both work on together every month. Maybe that second job is in a real estate field.
3. Sell her the dream: Not the real estate dream, but her dream! What does she want more than anything?- does not necessarily mean a consumer item. This goes with what Brian said, but take time to listen and find her exact needs/desires. Tell her how you want to help her realize her dreams- of security, nice house, travel, good education for the kids etc.
4. So you are now in less or no debt, your income is higher, your wife feels like she has a safety net under her, and is excited about her dreams. You have less urgency and more confidence in your voice. Real estate is a natural next step in fulfilling those dreams! Go for it!
Good Luck!!
