I was determined and wanted something that I could sustain for the long term for my family's livelihood and control the effort I put in and the results I got from that effort.I specialize in sourcing properties for fix and flip investors nationwide (wholesaling, but with real-world experience and closed profitable deals for myself and my investor partners) with a roadmap to acquire rental properties as finances permit.A lot of our deals are currently coming through organic search as I have a background in substantial traffic generation through search engine optimization and organic means.

And you still have $70,000 to go buy a single-family home or multifamily home, and now that you're on a bunch of wholesale lists where you can source deals well under market value it is easier to find good deals. 

Simple answer - yes you can alter your funding source after putting it under agreement if you chose to use a hard money lender instead - i would just communicate with seller that hey I was going to use cash (assuming you have it from your heloc) and instead will finance some of it but let them know its not contingent on financing.

You could also consider sourcing an inexpensive used vehicle as opposed to something new.

FF isn't the only source, of course, but it is one of the most well know.

I own one and use it from time to time, @Kevin S.The base of the Nix sits flush against the painted surface, and it has it's own internal light source.

The one cost will be getting the units furnished, but if you live in the area it isn't hard to source a bunch of decent 2nd hand furniture on Craigslist or FB market
