My first deal. In a bind!

[Taylor Silker]

I have recently finished construction on my first property at the age of 27. Last summer my sister and I came up with the idea of getting into possibly flipping a house. I live in colorado and she is a real estate agent in northern Minnesota. We decided I would come up with all the financing (7.5k) and she would GC the deal for her first time and basically do all the ground work and work on what she could. We then found a parcel of land which was for sale on the tax forfeit list for 17k. I put 2k down on the land and we found a modular house that has huge A-frame ceiling and a master loft so it doesn't look like a modular at all really. Anyways we put 5k down on the house and then went for financing. I received a construction loan for 309k which was an in house loan for this local bank that said they "stretched" the loan for us just in case. We didn't plan on spending all that money on construction with the budget we had planned but we all know how that goes. I maxed the budget but we are finally finished after 8 months of construction and having to finish the loft among other things. After all the hard work we put it on the market for a price that we know is a little high but obviously i would like to not loose money after closing costs and all that. We haven;'t had much luck on the mls so we figure we would do a little airbnb to help with holding cost. Heres the kicker. After only one week we are booked for 20 days in august and haven't had a vacant day yet since we've had it up. We will make at least 4k and our loan payment is about 1k on interest only as of now. 

Last time I spoke to the loan officer, she told me that we should sell the house cause she doesn't think i will able to switch to a conventional mortgage and keep the house. This has to do with my debt to income but my income has only got better since the start of the loan. Why the heck did she finance me for the construction loan if she knew I couldn't afford to switch to a conventional?! I spoke to another bank in the area and they said they couldn't finance me either. This house  is a potential 1.5% deal with good vacancy rates on airbnb. Is there any bank or investor out there that could finance me knowing this potential? 

As a young and devoted investor I would really appreciate some feedback and guidance on what i should do. I really want to keep this house!  Thank you all!
