As to buying land and build from scratch, make sure you understand what you're getting into, especially if you don't reside on the ground.

You will need 20-25% down and a commercial loan for the rest.Most lenders will want to lend to an LLC with you personally guaranteeing the loan.Typically, each MFR would be purchased under its own LLC, for liability purposes.Each LLC would then also need its own bank accounts for collecting rents and paying expenses.

This means that you will probably need to pay registration and filing fees in at least 2 states if you don’t buy CA property as a CA resident.Any lawsuits should be limited to the assets of the LLC and not your personal assets (assuming you run the LLC appropriately and the corporate veil is not pierced, some debate as to SMLLC).

Then, in year 11, you will begin paying down the principle amount of the loan over 20 years.
