@Logan Allec, yes, $45k is enough to loan on any real estate project, you just have to find the right investor. We currently have a $350k rehab project and a private lender is lending $30k on it. As a private lender, you don't have to lend the entire amount of the project, you could be a gap lender (not as secured, though), etc. Our fund just accepted an investor with only $10k, but they are getting 10% fixed with no fees.
Don't let the amount you have be a limiting factor, it is not. You want to lend on one of our projects, feel free! Kidding aside, there are a lot of investors that will utilize your funds, you just need to be sure to vet them properly and make sure you are secure. As an example, we often offer first time investors on our projects additional collateral. Since we own many other real estate properties, they will be secure via the property they are investing in, but they also get another property as collateral, so they are double secured.
