Thank you in advance for anyone’s time and response!

I am currently up a little more than $100k on my current home an I have an FHA loan on my current home.

Without experience and advanced planning it could be a net negative, PM nightmare, or combination of challenges. 

@Samuel Metcalf- thanks   1) I would recomend getting a HELOC in place on your primary residence duplex  for  as much as  possible...this should be available for  free or a low  cost and the rate will be variable in the  8-11%  range ...prime rate +  margin of  1-3% ) ...the min payment is in interest only payment on outstanding balance   2)  use the heloc for the  remodeling  costs ...pay it down as  agressively as you can   3) on the  purchase of the investmenet  1 unit -  you are  allowed to put as little as 15%  of the price for your down payment ...the pricing you get for the loan will improve  as your down payment  grows so you might look at  75% /  80%  and  85%  ltv  options 

we have until spring of 2025 until our balloon loan either has to be refinanced or paid off (we got this loan because we intended to build, of course) and now i feel like it's a ticking time bomb.we conducted "clean and satisfactory" (no issues whatsoever to build) soil and foundation tests and provided those to every buyer. it seemed (not quite sure here) like they backed out once they reviewed the tests - yet there is nothing negative in them. we will not be providing these tests moving forward (as we had to do them ourselves and feel that each buyer should do their due diligence moving forward!)

Due to inexperience opted for a 10 year loan which is going to clear in 4 years.

Hey John,You'll want a rough scope of work in mind before you give them a call so you can let them know in advance what they'll be looking at.

Luckily bank agreed to make repairs needed to pass four point.I had to get a renovation loan insurance policy where I paid for a year up front in escrow and they would pull $400 a month till renovations were completed and then I could find a new insurance policy and the remaining escrow would be transferred to the new policy.Paid $540 for an appraisal.

Any advice on networking or direct contacts would be immensely appreciated.Thank you in advance for your suggestions and support!

I appreciate all the help in advance and please feel free to ask me to clarify further on certain things!
