Fayetteville real estate investing is pretty good, though recently it's getting MUCH more competitive than in past yearsnone of the good deals in Fayetteville stay on market long. your best bet is to talk to realtors and hunt the market often, when a deal comes you need to move lightning quick.

Which might be steep but I just left my W2 job to start my own construction company full time.

@Jon Dorsey - I learned through Scott Carson specific to notes and my full time gig is in real estate development and construction.

I will build new construction fourplexes and sell some to raise capital but plan to finance and own long term as many as I can qualify for.The LenderI have a local regional bank who has a Mortgage dept and they will also do an interim construction loan once i am quailified for the mortgage.

The borrower has to settle the debt...it's not going away...and there are also late taxes I would bet...which are in first position in front of the mortgage.

@Luis Marcelino I manage multimillion dollar capital construction projects, so using an architect, engineer and professional construction cost estimator is standard.

Have you thought about seeking a construction loan. 

I’m currently employed as a mergers and acquisitions intern at a management consulting firm focused on the architecture, engineering and construction industries and I support both buy and sell-side transactions, but my passion lies within the real estate industry.
