@Rajagopalarao PaidiRecognize time is also money if you are financing it and I have found without an agent will take longer to sell.Also are you local where you could manage all the showings, advertising etc?

I advertise the houses that way, even if there's an appliance or two that the previous owner has left in them and I don't mention them so that the people coming aren't (or shouldn't be) expecting to find them. 

That would be like claiming people should ignore speed limit signs because they don't advertise the road, traffic or weather conditions.

But unless they advertise the seller finance (and be careful as most are really bad deals), then you'll need to talk them into it.

Why are they advertising that seller financing is available? 

There will be a lot of agents advertising their market, and while this can be annoying, it can also be helpful when searching for areas to look in. 

I recommend setting up keyword alerts for each area as they are discussed in the forums daily with advertisements posted in the BiggerPockets marketplace hourly.One thing to note when looking at the individual markets, you can make or lose money in any market.

I read some books and saw the late night advertisements about real estate investing, so I was very interested in this type of property.

I've seen some of those advertised also.
