Thoughts on buying my first apartment building

[Joseph Powell]

So i still new to the bigger pockets forum and this is actually my second post. I have 2 investment properties that i rent out, with one of those being paid off. 1 of my goals is to purchase a multi-family home or a duplex for the last 6 months, but in my area (corpus christi) prices are very high and no deals to be found. Well, i think i might have found one. An apartment complex with 10- 2 bedroom 1 bath, with 7 occupied already with 600 dollars monthly rent. The other 3 are just the shell and need flooring and walls etc. Could have the potential to bring in 6k a month with all of the rented out. With a 30 year mortgage payment of 2300. I was thinking of  doing a cash out refinance for the property that i own and use that for the down payment. This would be a big move on my part, since i am very conservative and try not to take many chances. The apartment is about 1 1/2 hours away from where i live at.  Maybe just looking for some advice
