So it's a 172 units selling for just over 31k/door running at around 95% occupancy. Can you describe the area? Is it in the suburbs, rural or in the city? Rents below $500/unit always come with higher operating costs. Tenants tend to give items that should have a useful life of 10 years about 3 at best. You get the idea. So I would by no means take the brokers advice. I would however talk to several property management groups in the area that manage larger complexes nearby. Try to set up a meeting to go over some items face to face. Then have them put together an operating pro-forma based on the property. A good, experienced property manager will not over sell you on the pro-forma. A few additional questions & comments:
-I see you have a gas and electric bill, what does the owner pay for specifically?
-Be extremely careful about deferred maintenance, items adds up very quickly when multiplied by 172. For example Fannie Mae multi-family loans require a GFI in kitchens & baths. Let's say it's three total per unit @ $35 each, That's $105/unit *172= $18,060. And that's just minor. A few small mistakes can add up to 6 figures+ very quickly.
-His 2014 actuals aren't accurate. Maintenance is low because he either neglected the property or added deferred maintenance items to capital improvements. When reviewing the tax returns review the balance sheet including all capital improvements. Ask for receipts, invoices etc. You need to account for on-site payroll & a management company (unless you are set up to manage yourself). Add work comp insurance into your payroll costs as well. You should be able to budget a full time maintenance and leasing/pm for the property. A good PM will source, hire & manage these people.
If the property isn't in a war zone or C- area then you might have a deal. However I would carefully look at the sub-market, demand, future supply, deferred maintenance, and utility costs. Your NOI will probably be closer to 400k at a glance. But on an 8 cap deal that's 5MM purchase price which is probably in the strike zone. However add in $5,000 per unit in upgrades/deferred maintenance and you just tacked on almost 900k. So it's really hard to tell you if it's a deal or not.
Is the property on the market or listed with a broker? I would be worried if it's listed and it hasn't seen strong interest. C class multi-family in the 100+ range is extremely hot right now with more capital chasing deals than available product.
