apartment at a complex
@Teyron Burden, I think we'll need more details. Is this one building within a complex of similar buildings that you can purchase or just one unit (like a condo).
I've got a property that is one building of a development that looks and is leased like an apartment complex. It's worked for me but I was confident in my numbers going into it.
There's good information on this site that'll help walk you through figuring out your expenses. That'll be the biggest part of your analysis to determine if it'll cash flow and determine your cash on cash return. It'll be up to you to determine if the level of cash flow is acceptable as it varies from person to person. Look for similar properties for rent in the area to determine market rents.
Careful of those HOA fees. Often that'll tip the scales to make it unprofitable.
