@Shaunte' Spangler-Drayton, if your gut is telling you this deal is too good to be true, you should trust it. The deal description says "Seller is willing to do the work if included in the price." I'd be wary of any seller who makes such a declaration. Every single time, I'd ask them to credit me on the purchase price instead. Repairs cost more than preventative maintenance. If they didn't care to maintain the property when they were the owner, why would they care to spend even more to repair it, if they're the seller?
Verify all the things. Never ever *ever* trust the numbers given to you by a seller. Either make that verification part of your contingencies, or build a margin of safety into your maximum offer price, so your deal is profitable even in the worst-case scenario.
Where does "$15,000 to make it rent-ready" or "$400 a unit Full capacity overhead costs" come from? I know your rehab budget is a full 50% of the purchase price, but it's still only $5,000 more than that $15k quoted rehab price. And there are so many ways it could grow beyond that amount. What if bad weather hits, delaying the construction time and increasing your holding costs? What if thieves rip out the drywall, in order to sell the underlying copper piping? What if the pipes freeze before they get a chance to do so? What if your permitting process reveals improvement work a prior owner had done, which wasn't up-to-code? I'm guessing the figures above are seller assertions, in which case you need to verify them with disinterested 3rd parties, such as a trusted appraiser or contractor. Again, add them to your running list of contingencies or ask the seller to deduct them from the initial purchase price.
I see you've budgeted 2% for property management. I'd budget at least 10%. Closer to 12% in a D-class area. In that kind of neighborhood, you want someone in place for whom this is not their first rodeo, and who will hold tenants to the agreements they signed in their leases, without exceptions. Not for the purpose of extracting every last dime from tenants. This is about avoiding liability. Making exceptions for one tenant can put them (and you) in a situation where you are legally obligated to make exceptions for all other tenants as well. Otherwise, you open yourselves up to accusations of selective enforcement (and therefore, housing discrimination). From a tenant's perspective, why would you let that other tenant (but not me) get away with rule XYZ, unless you are discriminating against me?
Another equally important reason to get a property manager- you want this property to be making money for you while you sleep, right? If you're managing the property yourself, you haven't bought an investment- you've bought a job.
Not sure how old the property is, but unless it's on the new side, you should be budgeting 15-20% combined every month for CapEx + Repairs. That's in addition to you initial repair budget. If I were bidding on this deal, I'd budget closer to 20%.
Call it a hunch.
You won't necessarily be paying this out to repair contractors every month, but you will need to set it aside for the day when a major expense does occur, such as an urgent roof / foundation / HVAC repair. When that day comes (and it will come eventually), you'll be glad you've prepared for it.
Vacancy is the silent killer of multi-family investments. One month of vacancy can cost you 8-9% of your revenue (which translates to 2 or 3 months of profit). So that's another expense you want to set money aside for. I'd say 10% at least, but talk to a local property manager about what's realistic, given the turnover in your area.
Find out whether your local county has an online Property Tax portal, and whether you can plug in the property's address to get historical tax data to use for your assumptions. Find out from local landlords whether tenants or owners are expected to pay some or all of the utilities, and how much those tend to cost in summer and winter months. Find out whether there are seasonal expenses such as snow removal or landscaping maintenance. Find out from the seller what repairs have been made to the property and when they were performed, then find out from county records office when the last construction permits were issued for this property, and what the permits were for. If those records don't line up with each other, press for more info or just walk away from the deal.
In a way, it's good that the property is completely vacant. That means you won't need to add a contingency to the sale about the current tenants' credit history, criminal background, income verification, etc. Furthermore, you'll be selecting the tenants, which means you can be as stringent as you like on the criteria. I've heard of landlords who require a walk-through of the tenants' current living situation, before approving their application. If that's not your style, have them meet you at the property and ask to inspect their car. That can sometimes be a good proxy for judging how they'll take care of your rental.
If this is your first deal, the allure of sub-$50k properties can be attractive. But you may be better off going with a B-class or above area at first, if only to get your bearings before attempting more challenging deals.
I know I'm a bit more paranoid / guarded / etc. than you may expect. That's because avoiding a losing deal is more important than finding a winning deal. If you lose out on a winning deal, there's always another one down the road. But if you invest in a losing deal which costs you 40% of your capital, your next deal must have a 66% ROI simply for you to get back to break-even.
