@Angel Troupe it really depends on the condition of your properties and how much you are willing to spend on marketing.
On one end of the spectrum you have little marketing money, the properties are in really bad shape/doesn't look too appealing online, you would want to shift your focus to getting investors into the house and seeing the value prop of the home as; "this home is fixer-upper which is undervalued and would be a great investment". Aka more traditional marketing.
The other side of the spectrum would be if you had tons of marketing money and the properties look very good online through either images and videos. In this case you would want to double down on online marketing. Get a single property website, post on zillow, mls, etc. use biggerpockets to connect with some other investors and list your properties.
Depending which spectrum you lean more too I can refer you to some resources that will help you market your homes.
