@Travis HardyCurious to hear how the appraisal goes.  

As you can tell, it’s a very competitive industry and many loan officers will do whatever it takes to get your credit pulled and pay for an appraisal. 

How much will the duplex appraise for once its fixed up?

I have had this goal of buying my first duplex and have talked to real estate investors, realtors, lenders, appraisers and have been encouraged so much to where I am anxious to dive into this.Now that I am 18 I have absolutely no debt, a credit score of 727, I have 28k sitting in a certificate of deposit, a couple years of working consistently under my belt, I’ve also been investing in my Roth IRA, I feel very blessed to be in this situation.I am still in high school, I know it wouldn’t be smart to buy a house right now but something in me is so anxious to buy this house I know I have to have patience but I don’t know if I should start the process of getting pre approved, finding a good investor friendly realtor, lender, preparing my documents or if I should just wait.When analyzing deals in my market I have crystal clear real estate deal criteria my strategy is house hacking a duplex, price range of 500,000-600,00 in Salt lake, Utah! 

It would depend on what the property ended up appraising for and what LTV you qualify for.

They will send an appraiser, you will have the option of financing up to 75-80% of the value.

He's doing a 1 bed, 1bath 1,000 sq ft cabin that appraises out for 525k and that we agreed to build for 400k all in (including lot, utilities, appliances) provided they get the construction loan or pay cash (they can refi out later) so we don't have any interest expense either. 

Will the appraisal be an issue coz we bought it for 370 3 months back?

It's by ordering an appraisal.

The appraisal costs on something like that would be pretty high as well.If you go the single asset route, you might get a nice little discount on fees by doing multiple at once.
