@Randall Marshall, As a rule of thumb, I estimate 10% for property management (rather than 7% which is what you are showing), 10% for repairs (which you don't have listed, and may not be that high for a building that new), 5% for Vacancy, and 5% for capital expenditures. It also doesn't look like you are showing anything for utilities (if they are paid by the tenants (other than the HOA), that is fine, just want to make sure).Also, your closing costs seem to be extremely high. If I use my spreadsheet (download it here if you want), I show a negative cash flow of $860/month.
There is a lot that goes into analyzing a property, and cashflow is just the tip of the iceberg, but if I were basing an offer strictly off of cashflow, I wouldn't offer more than about $450k for this property using conventional financing methods. If I could buy the property on terms (Seller Financing) that is a different story, and I could probably get the seller a full price offer.
