I have two other properties with that bank so if they make my life difficult ever I have a lot loans I can pull from them and move to other banks.

I'd say the logical paradigm in the question is a bit off.CRE includes everything from airports to golf courses to hospitals to campgrounds.So saying "residential versus commercial" is like saying "bacon versus plant life."

They are the best thing to add to your own personal knowledge, books, and podcasts out there.

@Camille Romerounless you are able to spend some significant time in your chosen location in person, and work on building a network there, i would pick a market closer to NYC, within a couple hours.  

I have personally wanted to build my home on this land for 10 years, as I've always been interested in this.Issue is, I've never done any work with residential development, only smaller land development, about 13 acres, and commercial, all on my own.With the residential development, I'm trying to get a sense of anyone in the space currently and what some ballpark costs might be for infrastructure and how that all works.

I personally have been an investor in Chattanooga since 2021 and the market has shown tremendous growth and strength, and I'm super optimistic for the future.

You are still going to have holding costs and a heloc will just have less holding costs that you would if you were doing a personal line or hard money. 

I tried changing useful life to 1 year but it doesn't change the line to show as an in year expense.

.: I would go HELOC for sure that would be best as others were saying the lower cost for the money changes between paying a higher rate for a personal line and typically personal lines they want a higher monthly charge as well independent from the interest rate.  

Quote from @Basit Siddiqi: I personally would not buy real estate with a retirement account.There are just too many headaches that are not worth the potential increased return.Some headaches when it comes to investing in real estate with a retirement account1) LTV values are less and harder to find lenders.2) Potential to sell or partially distibute the property if you have to do a RMD(Required Minimum Distribution)3) If you run out of cash and have to make a major repair, you may be out of luck and have to sell.4) Having to potentially worry about UBTI(Unrelated Business Taxable Income)I would personally invest in stocks/bonds/notes with a retirement account.I buy deals with cash and use a ROTH SDIRA so there are no RMD's.I buy at huge discounts to retail.
