Sounds like you need to do a little more 'searching' here on BP forums (and even Google) for the best methods on locating deals.
For one thing, having, "limited funds" is exactly why people start wholesaling properties. It's a great way to raise capital and less headaches than rehabbing.
First, join or attend as many local real estate investing groups/clubs as you can. This is also a great way to build your buyers list.
Two, be prepared to work. One of the biggest misconceptions is that wholesaling is easy. If it was easy, everybody would be doing it. Yes, the occasional deal does fall in your lap, but the fact is, wholesalers put in much time and effort to find deals.
A great starting point to finding deals has already been mentioned, driving for dollars. Also, try bandit signs. You can make your own with supplies bought from Home D/Lowes or online sources like eBay.
When looking for deals, keep in mind who your end user will be and what their needs are. From my own experience (I wholesale but mainly flip) I'll tell you that most wholesalers fail in 2 main (and critical) areas:
- They over-estimate ARV
- They underestimate rehab costs
Do some research on estimating rehab costs using the tools here on BP. For ARV, always use sales comps. Having a friend who's a RE agent or has access to the MLS is always a good thing, but lacking that resource, you'll need to get creative when finding actual market values.
Good luck and let us know how things go.
