Continuing on:
"would I have to pay taxes on the money if no home is bought?"
That depends on who paid what, and what kind of business it is. Since it sounds like this has already happened you need to see a professional. Also, where is the money now? Sitting in the bank waiting for the next property opportunity? Returned to the investor? With interest or not?
Money invested in a business is generally not taxable when it is invested. If the investment turns a profit, the profit is taxed. For example, suppose you bought 1 share of Tesla when it was $100 per share. Today it is $240 per share. If you sold your share, you would owe tax on the $140 increase in price (the gain), not the entire amount.
