Here's what I would first look for:
How is the condition of the roof? I'm gonna say a new roof is gonna run you $20,000-$25,000 but I am being very roughly approximate here. You're not going to get it done for $5,000, and you're not going to have to pay $50,000.
How are the air conditioning systems? Is it just a window unit for each unit, or is there central air conditioning?
How much do you HONESTLY and REALISTICALLY think it will rent for? I can tell you right off the bat that I'd be dumbfounded if all 9 units rent out for $900, or even 850 quickly, and speed is the key for the first year of cash flow properties imo. Without even looking at it, I'm gonna say its going to be more like $600 or $650 a month to make it in SERIOUS demand, and $700 a month might be doable as well. $700 and $750 a month would be even more doable if it is in a PRIME location in Daytona Beach, but I doubt its in a prime location (Im a Floridian too).
How much is it going to cost to repair? Your ability to rent out this property actually isn't going to even be that hard. I can already tell that this place is not bad...you just got to get it running off the ground. The big question is, how much are the renovations going to cost? 2/1 bedrooms will rent easily in places like Daytona Beach all day long, provided you undercut the competition by $50-100 (just for the first year as you fill it up with the first 3 or 4 families for this 9 unit).
If I were in Daytona Beach, this seems like something I would be willing to pay $270,000-$280,000 max for this (including repair costs). Or $30,000 a unit. I'm guessing there's a second floor to this property as well which is kind of good news imo (less square footage for new roof which I'm sure it probably needs). There's a good chance that the current owner just does not have enough money himself to rehab and rent out the place and is somewhat desperate to sell.
Assuming the electrical wiring and the plumbing is still intact, why not offer something like $140,000, and be willing to go up to $180,000? That would be about $20,000 a unit, and if you rent them out at $675 a month, you're in the money.
