It's important to look at th reserves of an HOA and the reserve study to see if there are any possible future assessments.

Your utitlies. If you are "moving up" to a much larger space, keep that in mind. My water/gas/electric/garbage are way more in my current house than my last.

Becky,
The normal PITI which stands for principle, intrest, taxes, insurance changes on a condo, remove the last I for insurance and substitute the HOA dues. You'll want your own insurance to cover you inside your unit but most insurance is in the HOA. Be sure to check and understand what is covered and what isn't.

There may also be PMI or Private Mortgage Insurance if you put less than 20% down for a Conventional loan.

On a FHA loan there is a financed MIP +a monthly MIP or mortgage insurance premiuim no matter how much you put down.

Also, flood insurance if the house is in a flood zone.

Finally, I would also ask for the previous owners ultilities bill so you can budget for those too.

PMI (Private Mortgage Insurance) if you will have less than 20% down, or unless our lender is able to avoid it with 2 separate mortgages.

Other than that, looks like you have it all factored in, other than budgeting for monthly utilities (it's always a good idea to find out the average heating/cooling bills of a house/condo prior to making an offer).
