Hey Kyle! So, there are a few options you can pursue here. If you don't have the cash reserves yourself to finance the purchase, you could look to either hard money lenders to fund all or some of the purchase, or look at finding some family or friends who trust and believe in you and would be willing to go in on the deal with you as private investors. Sometimes, when sellers are selling as "cash only," there can be problems with the property that they know about that would prevent the property from qualifying for any type of mortgage, so just be careful there and make sure to do your due diligence and have an inspection done if possible.
As far as hard money goes, BP has a great list of possible lenders who are open to financing purchases for first time investors, you may just be paying a premium in points and interest rates due to the risk of being a first time investor.
Hope this helps some! Best of luck and I hope it works out for you on this one!
