House cleaning businesses do really well here, but with a recession coming within the next 18 months, I would hold off on starting a business for now and lower your investment risk soon.
Two things to consider...
Times of recession, provided your idea is good, are FANTASTIC for taking gobs of market share from competition...
Why? Because during a recession the typical reaction is pull your horns in... Cut expenses. Layoff folks... Cut advertising.
A smart business owner will take advantage of that and ramp-up getting the market share their competitors are abandoning.
And then when we come out of the recession... BOOM! Your company is several rungs higher on the ladder than what it was previously.
Second point is that during a recession assets that wouldn't have been made available during the good times are suddenly much more affordable.

Case in point, I know one billionaire who made his money because of a recession. Prior to, his business was just your average business in this industry.
Recession started. Prices crashed.
He had a small firm with limited overhead but he had a good reputation.
A major player in his industry decided they had had enough and were dumping assets left & right.
This small business owner stepped up and was able to acquire large chunks of these assets with very favorable terms.
The rest is history. Of course the recession ended and this guy became the owner of major sports franchise.
True story.
