Hello Monty!
First, lets set some inaccurate information straight. There are a couple of companies out there that will let you do a cash out refinance with no income! Rates are high, usually in the high 8s or low 9s, and you may pay 2-4 points on the loan. But, you can go up to 65% loan to value with no reserves, or up to 80% loan to value if you have 12 months payments already in the bank (12 months reserves_. The harder part for you may be credit scores. These programs usually need a 700+ score. Last, like i tell many clients, "just because I have a program doesn't mean you will want it".
Helocs have many different ways to calculate income once you get outside of the bank world. Bank Statements and Asset Depletion can be used with helocs! There are plenty of banks across the US that also have a stated income heloc (in the Carolinas, First Citizens will do up to $100k with no income verification). You do not want to lie on an application, that is mortgage fraud. But what you make and what the IRS thinks you make can be two very different numbers. Credit is also going to hinder your ability to get a heloc, and lack of income for now.
Reverse Mortgages (HECM or Home Equity Conversion Mortgage) can be a FANTASTIC tool! The loan to value that you can go up to will mainly be determined by your age. Credit is a factor as bad credit may limit options, or may have the lender require you to put 10 or 20 years of taxes and insurance into escrow.
Last, there are several companies out there that will give you a "mortgage" and not have you make payments! These programs are called Equity Share programs. You are essentially doing a partial sale of your home. They do not collect payments, but when you sell your home they will get some of your equity appreciation. I have access to several of these programs but have not dived into them deeply. They do require these to be done on Primary Residence, and they probably do have a credit component, but may not have an income component to underwriting. If you are interested in these options, reach out to me and my team can go deep with a couple of our lenders that offer these programs.
Now, lets talk about credit. Credit Karma has a fantastic "score simulator" tool that you can use to project credit score changes (paying off balances, opening a new card, using an old card that has not been used in some time, just paying your bills on time for 6 or 12 months). I highly recommend you play with that tool to start getting an understanding of what things you can do to positively affect your credit! Credit Karma uses a Vantage scoring model (which we do not use in the mortgage industry), but the trend will be the same as mortgage scores. If you can get your Vantage Score up 50 points, you will see positive results on the mortgage scores as well, it just may be 30 or 40 points or could be 60 to 80 point increase vs Vantage increase of 50 points.
Another great tool to use is myfico.com. You can pay $29.95/month on their Advanced subscription and see where your actual Mortgage FICO scores are at! Cancel after you pull, unless you like the tools it offers.
If you go back into the workforce, you may need to be back to work for 6 to 12 months before your W2 income can be used. If you go back to work as self employed, there are some NonQM programs out there that can do a cash out refi after just 1 year of bank statements or P&L.
I would focus on credit, consider some alternative options to "free your Benjamins" out of your home, or even consider doing a partial sale of your home to give you capital to get back at it!
Here for you if you have any questions and good luck relaunching yourself!
