Only a very small percentage of real estate property is sold and bought without the help of a third party. This party is the financing party, and in most cases is represented by different in size and specialization banks. For example there are banks that offer real estate loans exclusively. Their plus is that they can provide you with all kinds of consulting, assistance and any amount of money you need.  However, their minus is that all the help is conditional upon great credit score from your part and of course quite impressive fees. Also, from your side. Such services aren't suitable for private property purchases, so about ninety nine percent of cases for such banks are business real estate loans.

If you aren't in real estate for a living and do not sell and buy it on a regular basis, then a private business loan will work for you better. Banks that provide such loans as a rule make the biggest chunk of their income through other services, such as online business loans or car financing, so there is no sense for them to charge you insane amount of interest. If they would, they would lose a lot of clients, so the moderate interest rates allow them to stay in business and help you. The downside is that such institutions won't be able to offer you the fullest set of real estate related services.
