LTV stands for "Loan To Value," which is the ratio of the amount borrowed to the value of the property. In other words, LTV is the result of dividing the "amount of borrowing required to purchase the property" by the "real estate price."
Although it varies depending on the details of the property to be invested in, it is generally said that LTV in real estate investment should be about 80%, or even less, and in many cases, financial institutions can grant loan approval when the conditions are met.
However, in cases where the LTV is much lower than the appraised value of the property by financial institutions, such as when the investment is available at a bargain price, such as in the case of real estate foreclosure auctions or properties for sale by property owners who are about to go bankrupt, it may be possible to obtain financing at 100% LTV.
