Is there a specific duration I should be pre-approving an inquiry within?

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.

Hello Terry, If you're looking to find houses that are in pre-foreclousure you can use a website like www.foreclosure.com and you can get the list of properties and start marketing to them. 

The last lender I’ve tried to get a pre-approval had a, imo, patronizing response saying,”Although lots of people talk on social media about buying a three or four unit property with only 3.5% down in practice it almost never works.”All lenders who I’ve tried to give a pre-approval for has tried to sway me to switch to a 5% conventional instead.

Sometimes they have a pre-determined amount they are willing to share, sometimes they say they are willing to pay but the amount must be negotiated. 

-22 years old-$50,000 pre tax income from business this year-80k in savings-30k in investments-pre approved for $350,000 (had to use parents as co-signers because I started business 2 years ago and didn’t make much first year)Looking to get into first house by house hacking a 4 bed 2 bath renting out 3 rooms.

However, if you feel you need their input earlier, you could offer to pay for their visit to walk the property with you pre-inspection.

The improvements needed to be completed within the 180 day timeline, so I did a pre-fab ADU.
