Should I use my TSP for down payment on a property,

[Gildas Dossa]

I am currently just learning about real estate investing by listening to podcasts and reading books. I would like to take action and start investing by purchasing rental properties. I have no savings at this point, but thinking about borrowing from my TSP (almost like the 401k but for military and federal government employees) for a down payment. The rate is around 3%, but I haven't found a property yet.

I had some advice for me to build my savings up first to be able to cover any expense that may come up, but I really want to start doing something.

In the end the question is, should I borrow from my TSP for a down payment or continue to learn and save up before starting purchasing? Thanks everyone.
