We just closed in late Dec so the financials are a work in progress but we’re projecting and tracking closely to a 55% expense ratio and should have about 11% CoC in year one through the renovation period as we get more renovated units online. 

If that is the case wait till your 18 and purchase a small multi family to house hack.

The landlord should be named on the tenant's insurance policy for additional protection and to assist with tracking compliance.

And then I see liberal areas for whom affordable housing is the cause du jour suddenly balk when multi-family density is proposed in their neighborhood. 

It seems like a win-win, especially with the simplified approval process and flexibility for multi-generational housing.

Also, you don’t need a business license just to look at properties, but if you buy a bigger property, like a multi-family unit, you might need a certificate of occupancy, depending on the local rules.For business trips, most expenses can be deductible, but if it’s part personal and part business, you can only deduct the business portion.

Selling before death would be a costly mistake   - you did not explicitly state this was not a multi family but it seems likely from your description.  

This applies both to single-family residences and multi-family buildings.Non-residential HVAC systems, such as those in office buildings, warehouses and shopping centers are eligible for bonus depreciation.

I am interested in buying a multi-family apartment complex.

DSCR or Fannie/Freddie loans can go up to 75% on single family homes, multi family homes (2-4 unit) max at 70% if you stick with Fannie/Freddie.Other things to consider would be:Paying points for a lower rate vs higher rate with no pointsIf going DSCR - Prepayment penalty term (0-5 years)The lower the loan size ($200-250k and lower), you should consider paying up to 2 points and doing a 5 year prepayment penalty if going DSCR.
