million in addition to their investors (who expect a reasonable rate of return) by keeping the rental rates at a fraction of the market rate?

I created a co-hosting profile as I was looking for additional opportunities.

When you move forward, they should provide proof and name you additional insured.

Figured there would be a few data points left out of the equation' that I would need to circle back with :) .There are additional units not rented at this time which could be rented to increase the income.

I think what @Garrett Brown is getting at is using this in addition to other methods.

if there is appreciation, but you wouldn’t sell your current home tax free and buy a neighboring home to rent out, (There by raising your cost basis for additional depreciation and lower capital gains tax.) then it probably doesn’t make a good rental property. . 

WIth the new FHA & Fannie Mae legislation, many lenders are forecasting the rental income from additional units, even if they're not a zoned duplex.

I recently completed one on a multifamily property and found it to be a cost-effective approach.That said, there are a couple of additional factors to consider beyond the code differences between a garage conversion and new construction:Coastal Overlay Zones – If your property is in a coastal overlay, building a ground-up ADU may require Coastal Commission review, which can add time and complexity to the process.

Recapture typically happens only when you sell the property.If you use the property partly for personal use and partly as a rental in a given year, depreciation and other expenses must be prorated based on the number of days it was rented versus personal useBased on the current tax laws and regulations, once you've taken bonus depreciation on an asset, you cannot "capture" additional bonus depreciation on that same asset in future years, even if the rates increase.In the 2024 tax year, the rate for bonus depreciation is 60%.

Your best option may be to increase the rent to cover the additional expense.
