Help me analyze this 5-family deal!

[Bradley Miller]

Looking for input on this deal.  This will be my first 5-family.  I have a couple triplexes and a quad.

Here is the info

Price is 370000.  Owner wants 25% down @ 6% for 20 years with a 7 year balloon.

I have only done coneventional financing before.  Although the numbers make sense to me, the house is in good shape, and the location is premier, I'm having those nervous thoughts being a newer, young investor.  Thank you for any input!

Rent roll:
Apt 1, 3 br paying $1200, tenant paying utilities (due for increase)
Apt 2 1 bedroom paying $1100 tenant pays heat and electric
Apt 3 1 Bedroom $1260, landlord paying utilities
Apt 4 Studio apartment w/alcove paying $1150, landlord pays heat and electric
Apt 5 2 BR w/office alcove. $1250 tenant pays utilities
There are 5 boilers for natural gas heat. The heat can be taken over by the tenants, however there is a
shared meter situation that makes it difficult for the tenants to take over electricity for apts 2 and 5.
There is room for rent increases, however, the owner has opted not to do so at this time due to Covid.
Total rent roll $71,520
Expenses (rounded off to nearest $100)
Insurance: $4,000
Taxes: $13,000
Pest control: $800
Water, sewer, trash removal: $4,800
Utilities (gas and electric) $4000
Reserves: $2,500
Total expenses: $29,100
NOI: $42,420,
NOI assumes self management. Apartments rent up very quickly with many applicants applying at
once. There have been no vacancies for the past three years, therefore vacancy factor may be
calculated at less than 3%.
