For you to not have some false hopes on some homes you might like, it is always the safest way to assume that the people you pay the rent to do not necessarily want their houses to be eventually owned by their tenants in the long run. A lot of homeowners would usually want to get rid of their homes and accept money from that by directly selling them to a buyer, since not all sellers would want to deal with a longer process. The real estate industry receiving all the success it wants can also be a bad thing for those people who are seeking for rent to own homes, since more sellers will want to directly sell them, and it would be more difficult in desirable places. If ever the real estate market is not as prosperous as it should be, and the home you want to acquire of is one that can be found in a not that desirable place, the whole process of rent to own home finding can be very easy for you.
The most basic option would be for a buyer to approach any seller who owns a home he likes, and talk to them in a way that they will accept the offer. Sometimes it can be an easy task to find a house in the market that we may like, and sometimes we realize that these houses have actually been on the market for a long time already. If a house is being stapled on the market for a long period of time already, chances are, the owners probably don’t like to have their homes rented to be eventually owned, and some of them are probably just not in a hurry to receive money. Needless to say, you will just basically have to find a home that you think will suit your preferences, talk to the owner and sway him or her into having you rent the house until time comes to finally own it, and just pray afterwards that the owner will accept your offer. If you have already known, all of these transactions are pretty much negotiable, so be sure that you can talk it all out to the seller and have some terms ready wherein they will be able to profit as well and always know that it will always be up to them on whether they will agree with you or not.
One more option, if ever you are bad at negotiating, would be to find services that can allow you to rent to own a house you may like. The services and the sellers who provide these kinds of services will basically give you a list of homes you can rent to own, and they will also supply you with some contracts that you both will need to agree on, as well as some other processes that will be needed to complete the purchase.
