If at a future point, we wanted to use a unit as a professional office, would that change the loan terms?

Being only about a year into my investing career I'm still very green and don't have many re investing relationships other than my loan officer and realtor.

Hello,Trying to source deals, I've been reaching out to many RE pros in my market (Spain) and came to be in touch with a family office that offered to sell me, among other overpriced assets, the whole fifth floor - subdivided in 2 apt - of a building they're renovating in the city center. 

Feedback regarding your personal experiences rates changing; hidden fees; closing on time; professionalism of the loan officer you worked with, etc., are all appreciated, for the below listed lenders, and we are open to new suggestions for lenders not listed

Which isn't too unrealistic because they don't have any debt (eXp is cloud based and doesn't have buildings/offices)

Find a good lender/loan officer.

We use Appfolio in our office and love it, and I know there are people out there who use Turbo Tenant as well, I actually met their CEO at a conference and he was extremely knowledgeable of the struggle in keeping track of it all.  

Its why i travel to the Market I spend usually 2 to 3 days my office does a deep dive into MLS stuff..

Over the years I picked business degrees, real estate license, tax preparation training, loan officer licensing and training, investment / CFP training and it is all tied together in one big connected body of knowledge that emphasizes appreciation, debt pay down, cash flow, and tax write-offs...  

I used to be a loan officer, however, I will for sure refer you to the experts as I have since transitioned to being a realtor!
