@Chandra Whittaker you have received some amazing advice from this group here! It is heartening to see so many willing to help you and others on the road to success! It might not be a bad idea to share this thread with hubby to show him the incredible advisory board you’ve created so he feels more empowered as well.
You may need to show him the numbers and present it as if he were a private lender. Show him the breakdown and effect of refinancing, new mortgage payment, rent expected, allow for reserves, and cash flow on this rental. Then show him the cash received from the refi and how it can be used to purchase your next cash flowing rental. Show him the cash flow per month and how it surpasses having a second job that will only result in paying more taxes and nothing else. Show him the real tax and depreciation benefits of owning rental property and how it may offset your current earned income and reduce your tax liability (discuss and confirm all this with one of the amazing real estate CPAs here on BP). Passive income from rental property cash flow is better than a second job!! And if you’re in an appreciating market, icing on the cake as far as future property value. Some people just cannot visualize or grasp the numbers and need to have it all laid out in front of them.
As @Jerry W. mentions - fear is very powerful until you are able to move past it and realize there was nothing to fear afterall, assuming you've done your homework and you have a team of professionals to help you. Also, you may wish to find a local REIA group in your market, and bring your husband along to help educate. Real estate investing is a business with many facets. He may realize that being a business owner has far more advantages to building wealth.
Best of luck to you and your family!
