I need your opinion BP!!! Semi Ethical dilemma.

[Ryan Boren]

Hey BP, I have submitted an offer on a duplex in my area. All of the numbers add up as far as the property itself but I am torn on how to proceed with the mortgage on the house. Both units are currently occupied with one tenant having lived there for 6 years and the other for 14 years. I have a pre-approval letter in the amount of 55,000 and the bank is asking for 14,000 down not including an additional 4 - 5k in bank fees, inspection, and title fees. In total I would need close to 20,000 on the safe side to close on the property. This would drain my investment account completely which I do not want. On the other hand, I can claim i am going to live in the property (owner occupant) where the bank will then drop my interest rate to 3.6 from 4.5 and only require 4,000 as a down payment. I total I would need a little under 10k to close the deal. This would leave me a comfortable amount to seek other properties. I do not want to put a tenant out, but I have been thinking about saying I planned on moving in and am having the current tenants watch the property for me. I would just collect some money from them but not have a current lease or month to month contract for only one month. After the month I would have them sign a lease or rental agreement and say I am no longer interested in moving in. Okay it gets a little better I am not a Total outlaw. I really am looking for a new place and have my current townhouse on the market, but have not had any offers. I technically would move in if I could but don't want to pay on two different places and make a huge move. I am not sure if this is illegal as I would be acting in good faith. There is no time limit I would have to live in the property because it is not an FHA loan. I could stay for a month and then decide to move. The banker round about told me, without me asking, that they do not check and frankly he does not care because either way the bank gets their money. But my question is specifically, does my idea sound immoral and is there another option? Any help would be much appreciated. Thank you, Ryan B.
