widower : Sell or refinance to rent after rehab

[Vincent Carter]

been living in a home with my wife for over 25 years... wife past away in 2018 went into financial difficulty around 2005 when her illness was getting worse so we got a home modification loan in her name only... which helped us from selling our home. since 2018 I am the estate executor and been paying for 3 years now. January of this year started Remodeling... home is worth about 550k after rehab owe 400k. want to keep house if possible to rent after rehab. I probably know the answer already of what I should do, but would like to hear any other options if possible thanks
