Ok Judy. So sorry about the delay! This is how I understand your current situation.
You are 52 years old, retired on disability. You currently own the house you live in, but it is on the market. You (and the bank) own a rental house which currently pays its own mortgage, insurance, taxes and some on your HELOC. You also have a car loan and a loan on some property (which you are trying to sell).
You have no separate emergency fund, but you do have secure income that covers all your expenses. You also save about $1,000 each month. When the kids are fully fledged, you'll have more to save.
When you sell your house, you will pay off all the loans (car, HELOC, mortgage on rental if you decide to live there).
One of your disability incomes ends at age 65. After that, you'll have about $82,548 annual income, only some of which is cola'ed. This is where my speculation starts: You expect this income to be sufficient (even generous) at first, but by late life 85 to 100, you are not sure this will be adequate due to inflation.
You currently have $190k in an IRA in cash or money market or something similar. Right now, that is the only money you have to invest. If you sell your home, after getting rid of any debt you have, you expect to have more to invest - maybe $100k or so.
You have two questions.
1) Do you have enough money?
2) How to invest the IRA?
I can't help much on question #1. I'm not qualified in any way to judge that other than just a layman's guess. Assuming the advisor is right (and I do assume she is right) you are doing everything the advisor suggested - sell the house and save money now. So I'm guessing you do/will have enough money.
About how to invest the money you have, here is an opinion. Ordinarily, at age 52, I'd be comfortable with 30% to 50% in bonds and I think you are thinking somewhere along the 30% bonds theme. You, however, are no longer in accumulation mode (or accumulating much, anyway) so your emphasis needs to change from "growing your portfolio" more to "preserving what you have, while having some growth". If you choose a 70% stock/30% bond portfolio now, you must be prepared to see 35% of that portfolio disappear in the next downturn. In other words, your $190k could drop to $124k. I'm not sure you should be on board with that.
I'm thinking a stock to bond ratio of 50%/50% is more appropriate. With that, you would likely not lose more than 25% of your portfolio in the next downturn. And there are still enough stocks in there for continued growth.
Whatever you decide, one of Vanguard's Target Retirement Funds would be a perfect investment for you. Target Retirement 2010 holds right at 50/50. Target Retirement 2015 holds about 60% stock/40% bonds. Here's a website to check
these funds out.
The target retirement funds are rebalanced for you and they creep toward a higher percentage of bonds as time goes by. If it is creeping too fast, you can just exchange some or all of the fund for the "next youngest" fund to achieve the stock to bond ratio you want.
There are numerous other ways invest your money, but this is the easiest. Does this idea appeal to you?
Now, when you sell the house and have more money to invest, you need a different approach, maybe. Since you are in the 10% tax bracket, it may not matter much.
For a higher tax bracket, it would be better to hold your bonds in the IRA and your stocks in the taxable account. Here's an example.
$56.5k Vanguard's Total Stock Market
$43.5k Vanguard's Total International (soon to be large, mid, and small cap, also containing emerging markets) 15% of portfolio
$45k Vanguard's Total Stock Market
$145k Bonds (split between Total Bond Market and TIPS) 50% of portfolio
This idea is almost identical to the Target Retirement Fund, but split into its components for tax efficiency. Again, in your tax bracket, I'm not sure it matters much and you might prefer to hold a Target Retirement fund in each location for simplicity.
One last idea - when you are much older, say 75 or 80 - you might consider a Single Payment Income Annuity (SPIA) for half your money. It would be like a pension - pay you a certain amount each month - guaranteed income. Don't look at other types of annuities as most are not in the purchaser's best interest.
Mull these ideas over and let me know what questions you have.
