The IP and oi as the money matters are related yes! and similar yes! but not the same yes! Meaning, the investments can share similar io as the IP. The investments may not be the same. Like endowment savings as capital investment, in how they where raised as the savings investment to the redeem plan this may differ or share properties in one way or another as the scheme or plan. Example, comparing to the pension funds investments, the redeem plan may be similar as pay-out coupon/salary. The properties IP referres to the investments schemes associating their plans as how the savings or settlements for the investments are made. The io, noted for the investments can be the dividends, the share earnings incentives from the investments holding firm or the pay-out plan. Closely the same as the IP.

Oh thank you, is there any studies that can help me on my concern Sir Siyabonga Chule ?

I warmly welcome! You should formulate a more precise question, because it is not known if your question concerns investment in real estate by investment banks or from the point of view of a commercial bank client. Of course, the return on investment in real estate can be linked to profitability in other assets, either directly or vice versa. It depends on which other investment assets we take into consideration, what is the economic situation of the country, at what point in the economic cycle is the domestic economy, what is the situation on the real estate market, whether this economic situation is largely generated by commercial banks is the credit risk, which banks approach to borrowers who take out mortgages. In addition, regarding other investment assets, the key determinants are: what is the situation on the capital markets, including securities, raw materials, precious metals, what is the currency situation, currency risk in international transactions, the value of the national currency to other currencies, besides general macroeconomic situation, inflation, unemployment etc. I invite you to my profile, I describe in some of my publications these issues, relations, dependencies on capital markets.
