I am planning to get mortgage for purchasing multi-family property upto 1.5M and wanted to know what would be the best options.

Make sure your plan is rock solid, unlike hard money, you can't pay a point to extend the loan.

We sold for 10k more than planned and came in a tad underbudget.

Consider Consulting a Professional: If you’re unsure about any aspect of property taxation or need assistance with assessment appeals or tax planning, consider seeking advice from a qualified real estate attorney, tax advisor, or property tax consultant.

What's your plan with the proceed?

My plan is to purchase single family homes/townhomes for long-term rental, and benefit from appreciation over decades.

I assume you plan to use an PM?

I had planned on doing the work myself!

We are planning to live in the owner's unit and tenants above have lease that is expiring mid 2024.
