Most hard money lenders are going to require 10 -20% down payment and then require you fund bring 10 - 20% of the rehab budget depending on your experience flipping (in your name/LLC you own), property ARV, etc.

Now if you want to buy and live there forever or you want a specific location or lifestyle or the amenities, might be something to consider, but not for investment....they're for living.Your best option right now depending on your income, is probably to buy at least 4bed house or 5 bedroom if you can make it work financially and rent bedrooms. 

I am not saying that to brag, the reason I say it is we all wish we could get into real estate at a younger age - but we are all different and depending on your level of risk, sometimes being patient is not a bad thing as its a marathon not a sprint.  

Like most things in real estate, a lot depends on the circumstances of the individuals involved and not just the numbers and figures.I hope this helps explain my thoughts, and I apologize for the lack of clarity when I defined "arbitrage".
