Will I Have a Problem Refinancing after Buying Cash?

[Alexa K.]

Hi all! I'm finally ready to make the leap and purchase my first buy-and-hold rental property. 

I've recently found one that I like a lot, however they want cash for it. While I have about half the cash on hand, I'd like to take out a personal loan to purchase the home in full and then take out a mortgage on the home for about 75 to 80% LTV, like I've read quite a few people do here. However, I'm worried that I'll run into issues with taking out a mortgage for whatever reason.

So my questions are: Are there any circumstances where I won't be able to refinance? How long until I can take out a mortgage on the home after purchasing it in cash? I'm afraid of being stuck with a 7 year personal loan for longer than absolutely necessary.
