My experience has been this. I have 2 houses on rent to own. I initially listed both houses for sale on the MLS, mainly because they are in areas considered a little distant from the city, and the commute is further than average. I had maybe 10 veiwings in each home over 3 months. As an investor, this is simply too long to wait and, to be perfectly honest, I cringe when I have to pay an agent a 5% fee. I see people recommending agents all the time as part of "your team", but personally, I have never use an agent any more to buy or sell houses. A different topic, though somewhat related to my RTO experience.
Anyway, once I told my agent to pull the property off the MLS, I put up a Rent to Own ad on Kijiji. The response, in comparison, was pretty impressive to say the least. I had about 50 calls inside a month. Now, not all these people qualified, for one reason or another, but I went down the path (to the contract stage) with about 2-3 different potential buyer tenants on each of my homes. Each qualified in their own way, each had resources to afford my house, and each had different reasons for not wanting or being able to buy through the bank. You'd be amazed the stories you hear.
I have actually had one of my clients / tenants transfer their interest between the two homes I own. I make sure that they go into the entire process with no doubt as to what would happen if they decide to back out. To the extent that they sign the actual line in the contracts that specifiy that they forfeit their deposit and rent credits if they have to walk away. This has happened to me twice as people have moved to Alberta (imagine that!), and I have been able to quickly re-list and pre-sold my houses on RTO all over again.
The answer to your question is have you advertised an RTO? Have you tried to sell a house? Are those two classes of people the same? I'd say not. Many people respond to RTO who are not able to be in the market to buy a house. From my experience, there are a great more people out there that really want to own their own place, but just do not have the appropriate situation to be able to do it. RTO is an option that these people can look nto.
Finally, I take a little umbrage (spelling?) to posts claiming landlords like myself take advantage of misinformed buyers. I personally tell people what they need to be making in order to buy my house 2-3 years down the road. My contracts clearly outline the terms, and I tell them upfront, in plain English, that they are essenatially makign a decisiont oday, to buy my house in 2-3 years, and they have the keys to their home today, instead of waiting for 'never' with a bank. All my RTO clients / tenants have had 6 figure incomes, and for various reasons, cannot qualify or have other reasons for not wanting to buy the house today.
Sorry got carried away. While I am not in the business of RTO per say, I do have two properties that I consider necessary to RTO, simply because of logistics. I found it easier (and more lucrative) to find RTO buyer / tenants, than sell the bloody things on the MLS.
