The interest you are paying on the loan is paid back to your own retirement account so you are in essence helping it grow and if your money were sitting in a money market earning 0.5% it would make sense to take the loan out and pay interest to your own retirement account instead of some creditor and this would also mean that your 401k is getting guaranteed 4% interest.All of the above and more need to be taken into account in order to decide if this would be sound financial decision. 

Don't offer to mediate, don't offer to make a decision in "favor" of one or the other.  

Hello everyone,I'm on the fence with this investment decision since it is life changing!

In the meantime I let the runner up know that we'll have a decision within 24 hours, but it looks like we'll be moving forward with the other applicant. 

Now I can make that decision from my office and others like it. - this one of possibly thousands of small mechanical steps that go into the decision making process during renovation and flip projects.

Then make a decision on who to contact from there.Also, make sure to be specific when asking them what type of law they practice.

No, you don't have to do it if the project is not a solid business decision to pursue.

Let's look at the rates and differences and what I'm trying to make my decision on:FHA 3.75% interest3.5% down.PMI through the life of the loan.Higher insurance premiums.A little higher mortgage payment.Conventional fixed rate4.25%5% down.PMI drops at 20% loan to value.Lower insurance (me and the lender calculated nearly $100 month difference roughly)Slightly lower mortgage payment.Now with this information I was provided the conventional is a no brainer as over the long term and beginning costs are less. 5% down is my max for down payment I can do in order to cover all other fees to seal the deal.

I always like to leverage local knowledge before making a decision.

Add to all of this that the listing was incorrect.
