i.e. if rent is $800, monthly income is $400? sounds too good, no?
No is correct. With the $400 left over, you still have to pay debt service. Even if you pay all cash, you still must decide if the cash on cash is worth the investment and the JOB (dont be fooled, being a landlord is a JOB!)
zillow has it for 110k
Never, ever, ever use or base your numbers off of Zillow "Zestimates". The ONLY thing Zillow is good for is to find the actual sold figures (which are true comps) and perhaps the current listings to give you an idea of what your list competition is.
So far, you have received advice to move on from this investment from several posters, of which, several are very experienced, yet you appear to keep coming back to make this deal work. In history, that is a recipe for disaster.
Keep emotion out of the equation. Your hunger to invest should not overcome common and savvy investment protocols.
Condos can be tricky due to HOA's, and the fees involved create a higher operating expense than units without HOA's. They can be harder to sell, but on occasion, market dependant, can be what sells.
I would personally consider condos to be a more advanced strategy for those experienced in doing so with proven track records. Please don't make this your first investment.
One more thing, your statement that the unit sold for $130k in 2004 means nothing. The only thing that matters is what it is worth now and what your market is doing now. 2004 was a phenom year for RE appreciation and should be disregarded in analysis as it will likely not repeat anytime within the next two decades.
