You can get some very favorable funding and you'll need to occupy one of the units for just one year. 

If you refinance the property that you used funds from your TSP loan to purchase, are you able to pay back the TSP loan in a large sum?

What do you have in funds and experience?

I have some cash, but likely not enough to fund a purchase without bank financing, and especially not when factoring extensive rehab costs into the equation (may need to up my knowledge on creative financing to bridge this).

You want to know of any & all problems before spending any additional funds on the property!

Do you use a title company?

Quote from @Brandon Blackmon: @Bruce Woodruff 100% the answer I'm looking.... a solid GC, has a 20-25% markup to I would for sure know going into this that these are private companies and they can set their own fees. 

I would like to know how the process of building loans works and how much funds I need to have.

As for the initial investment, I am working towards securing the necessary funds and am open to exploring various financing options that can facilitate this.Despite facing numerous challenges and setbacks on my real estate investing journey, I remain determined and resilient.
