Dear Helaine: My house is in a booming neighborhood in an "it" city. I only have a $50,000 mortgage. The property would appraise for about $300,000. It's a large lot, with a house and detached garage in so-so condition. It needs some work.

I would like to buttress my retirement savings, and I have two ideas of what I can do. I could subdivide it, and then sell the lot for a pretty penny. I would lose my garage and most of my yard, but I would have a chunk of change in the bank, which I could invest in my retirement.

Or I could tear down the detached garage and build a new one with a granny flat apartment to rent above it. I could then do a traditional rental or Airbnb. (I'm leaning toward the traditional rental.) A friend of mine recently did something similar and, based on her experience, I speculate this would cost me about $125,000. Based on what rents are where I live, I believe I could rent the apartment for enough to cover the increased mortgage payment and other costs. What do you think? -- Home for Good

Dear Home for Good: The personal finance community likes to promote earning money as a landlord as "passive income," but it's frequently anything but. Tenants can call in the middle of the night, short-term guests can be wonderfully charming or a difficult handful. Either way, the person living in your property will be a most definite presence in your life. Expenses are often somewhat more than you expect -- you are now maintaining two properties, not one. You've doubled the number of sinks and roofs that can spring leaks.

That's not to say selling the land is an ideal situation either. It will cost you money in the long run -- homes lacking a detached garage or decent yard space do sell for less than those with them. You will, moreover, be living next to a construction site, and you'll ultimately have a neighbor you have no control in choosing living very close to your home. A difficult tenant is a relatively temporary problem, but you'll live next door to a problematic neighbor for a much longer period of time.

If you still want to go ahead after weighing all these pros and cons, I suggest sitting down separately with both a real estate attorney and an accountant. You want to know the laws regulating both short- and long-term rentals in your neck of the woods, and then you'll also want to run the numbers with someone knowledgeable, objective and neutral. You need to know whether you have a financial cushion for contingencies ranging from the inability to rent the property out at the price you need to paying for unexpected repairs. If we want something, it's easy to underestimate the potential expenses and make the numbers work in our head. It's harder to fool a professional.

Hi, Helaine: My parents and their surviving sisters and brothers are getting up in years, so my family began to rotate hosting Thanksgiving among the next generation. This year, I'm up.

We are expecting somewhere between 20 and 30 people for Thanksgiving dinner. It's a family tradition and I enjoy it, but only when I am a guest. I am busy at work. So is my husband. My company doesn't give Friday off, and I doubt I'll leave early on Wednesday. I don't want to give up a vacation day.

What I want to know is if I can cater Thanksgiving dinner and ask my family to chip in so we don't need to put a several-hundred-dollar bill on plastic. I think that's not good etiquette, but my husband says we need to stick to a budget, and Thanksgiving dinner for my family isn't in it. Who is right? -- Turkey Blues

Dear Turkey Blues: Let's take Thanksgiving out of the picture. You are hosting a big dinner party, and you decide to cater it. Would you ask the guests to chip in? The answer is obvious: of course not -- though if someone offers to cover their share, you might take the money after a polite protest. On the other hand, there is something you could ask from your party goers: potluck.

Here's my advice. Write an email to everyone attending. Explain part of what you told me -- say you are busy at work, and you are going to cater the dinner. I'd add a line about how much you are looking forward to hosting, but in the interest of making the meal still feel like the traditional event your family enjoys, you are asking everyone to contribute one dish. My bet? People will step forward to make or bring the salad, the side dishes and dessert.

To sweeten the deal, offer to make one thing yourself. Then a turkey and one or two other items shouldn't be a budget-buster, or at least I hope it won't. And maybe you'll get lucky and someone will step forward to handle that, too. But even if that doesn't happen, don't feel guilty. Surveys show more than half of us will encounter at least one item from a restaurant or supermarket at our annual meal.

As for your work circumstance, I'm sorry. But even if you had the entire week off, I would still say the same thing. It's OK to not want to spend hours cooking for Thanksgiving, so you can enjoy the day without working yourself to a nub. Cleanup will be hard enough!

Dear Helaine: I keep reading from multiple sources that the best advice for investing is to invest in low-cost index funds, like with Vanguard, rather than trying to buy and sell individual shares of stock. But I've been using a financial adviser with a major brokerage for years who is doing just that with the $130,000 I have in my IRA. It's diversified, and it's doing fine but not stellar.

Should I sell all those individual shares of stock and roll this IRA into a low-cost index fund? Is it a bad idea to let my financial adviser know this is what I want to do? I'm not sure if I need her cooperation to withdraw the funds and roll them over. For background, I'm in my 30s and have a long way to retirement. -- Want To Do Better

Dear Want To Do Better: We need to start with some education. First, you do not roll over an IRA. That's what you do with a 401(k) you want to put in an IRA. If you want to sell holdings in an IRA, you do not need to withdraw the funds. You can, and most certainly should, do so within the IRA.

If what I think you mean is that you want to move the IRA to another brokerage or mutual fund firm like Vanguard, you can do that, too. It's called a transfer, and it is something you do not need your adviser's permission to undertake. You can fill out a form on the website of the firm you want to move the funds to, and believe me, they make those very easy to find on their websites. It's quite possible your current firm will not sign off on the move until you fill out a form with them as well. That's easy enough to do, and again, it most certainly doesn't require the consent of your current adviser. Got all that?

Now let me get to the meat of your letter. The studies show very few people -- less than 1 percent -- possess the ability to beat the markets year in and year out. That doesn't just mean me or you. It also includes financial professionals like your financial adviser.

Moreover, I don't think individual stocks are for you. Based on the questions you asked me, I don't think you have the financial knowledge to engage in stock trading, or to permit someone to do it on your behalf. There's no shame in that; you don't need to be a financial expert. But it does point to the fact that, as you suspect, you would be much better off with a combination of a total stock index market fund and a bond fund, or even a target date fund for retirement consisting of underlying investments in index funds. So what are you waiting for?
