Hi Victor Eng
Gilbert Dominguez makes some good points and that sounds like a good route to go. Another thought is how willing you are to sacrifice your personal living situation for awhile. Assuming you're past your first year (or whatever other term your loan may require if you are required to use it as your personal residence), and if you have a family they are okay with it, then you could move to a lower cost living situation and rent out your initial house.
Some options are temporarily staying with family, finding the cheapest rental you are comfortable with, finding a friend with extra bedrooms willing to rent to you for a short defined period of time, living with roommates, etc. Essentially, you're looking to trade your current situation for a materially lower cost situation. Should generate you a bit of extra cash flow if, for example, you're current situation costs you $1000 a month and you can find something for a lot less than that. I'd want my exit options defined before doing that or have a situation where I could be there longer as there may be issues with getting a bank consider the rental income your first property is generating with regards to length of time you're generating that income when you go looking for that next loan.
Some things I've personally done:
Lived with family and rented out my personal residence. I basically needed to be out of the area for two years and wanted to keep my place and was lucky enough to stay very low cost with family and basically bank the rent payments every month.
Lived for 11 weeks in Washington DC for $900 total around 2007 in a decent area. Basically needed to be in DC for a summer internship and was making decent money but figured I could pay for a trip to Europe by renting cheaper than what a lot of my friends were doing. Found a house rented by a bunch of grad students where 1 was studying abroad for the summer and I took over his portion of the lease for that time. The more applicable point is you can save tons by living with roommates, which I've also done.
Also, have you considered whether you'd be willing to rent out any extra bedrooms in your personal residence while still living there? It probably won't make a difference getting the second loan, but it's a way to generate income without having to get a second property.
Hope this helps. Good luck.
