In a total of 200 words, write two paragraphs with about how interest rates affect our purchasing decisions.
Identify the topic sentence in each by underlining it

"In times of high interest and probably high inflation..."

if you have cash, in times of high interest and probably high inflation, you may wish to spend rather than see your capital depreciate in value. If it is high interest low inflation you would want to invest your money and not spend. If you are planning to borrow - high interest rates make this less attractive and so disincline you to spend. If inflation is high as well, you may buy and bank on your debt decreasing in value over time. the higher the annual percentage
rate charged on a mortgage, the larger the mortgage payment. In general, for
every percentage-point increase in the rate, you pay about 10 percent more
per month in your mortgage payment. Although the increase is not proportional,
this is still a good rule of thumb to use for a rough estimate.
you should decide on a home based
on your financial goals and your present and future needs. You need to consider
all the costs of homeownership before buying. It’s important to shop around for
the best terms and rates on your mortgage and to know how to qualify for the
mortgage you want. If interest rates drop, you can consider refinancing.

To identify the topic sentences in each paragraph, we need to look for the sentence that introduces the main idea or the central theme of the paragraph.

In the first paragraph, the topic sentence is: "If you have cash, in times of high interest and probably high inflation, you may wish to spend rather than see your capital depreciate in value." This sentence introduces the main idea of how high interest rates and inflation can affect purchasing decisions.

In the second paragraph, the topic sentence is: "The higher the annual percentage rate charged on a mortgage, the larger the mortgage payment." This sentence introduces the main idea of how interest rates affect mortgage payments and the importance of considering all the costs of homeownership before buying.

As for the clarity of your writing, it may be helpful to fully develop your ideas and provide more explanation or examples to support your statements. Additionally, organizing your thoughts into separate paragraphs with clear topic sentences can improve the overall coherence of your writing.
