Hey Nicholas,Like you mentioned, I'd pay the high interest loans off as quickly as possible. 

You will generally want to make sure you are compatible and have similar visions, clear responsibilities of what each partner will be doing, and can openly communicate with this person.At a high level, though, what does "finding a partner" mean to you?  

Several large developers have built beautiful high end condo feel student apartments super close to campus which initially depressed rents in houses.

Ensure they send pictures and reports so you can monitor progress.4.Hire Trusted Contractors: Work only with contractors who come highly recommended by people you trust.

That neighborhood has low inventory, but very high rental demand and the tenant class is typically pretty solid.

This is because they didn’t budget properly and rent wasn’t high enough to cover actual expenses (repairs and maintenance, cap ex, vacancy and loss, tenant damage and turnovers, etc don’t expect to have any money left over after all of these expenses are accounted for if the rent is less than $1,500/month). 

Is it high interest rates, finding reliable lenders, or something else entirely?

Don't mistake high cost for low risk. 

This includes but business and personal filing and I’m curious if this is high, low, or right in line with what others are seeing.

However, a lot of condominium communities have clear guidelines on rental restrictions that often prohibit leases less than 6 or 12 months.Before paying for a really nice high-rise, please make sure you will be able to monetize it the way you'd like prior to purchase.Best of luck.
