First Duplex Help!!!

[Nick Diecidue]

My wife and I are looking to purchase 2/1 and 1/1 duplex in New Orleans, with long term tenants on each side, with a HELOC then refinance after a small renovation. Current rent is 1500 a month total with the landlord paying the water bill. The 2/1 side needs about 8-10k for it to become a 3/2. Right now, Our plan is to wait six months to due the renovation and have the tenants sign a six month lease for the current rent. We are going to inform them of the renovation along with the rent price increasing before they sign the six month lease. Does anyone have any suggestions or recommendations on what other options we can do?
