First ever investment property!

[Llamier Guzman]

Hello people! Soon I'll be purchasing my first ever investment property (Virginia) (MFH) and I honestly feel like I made a mistake. I'm currently pre-approved but my lender gave me a "mid-level rate" which I believe isn't my actual rate since I haven't chosen a property but me not being as educated on the behalf and thinking it was my actual rate I decided to rate shop a bit. My credit was pulled twice (currently sitting at a 700+ according to Experian) but I don't know if this would affect my score or anything when it come to actually choosing a property and locking in a rate. Did I rate shop to soon? Will this affect anything? what are the cons here. I would like to be educated on behalf of the "lending" procedure if that's okay!
