I'd find a lender that can do deals with brand new companies and do not require seasoning, if you choose to go that route. 

Started working with lender and title company getting everything ready for closing. 2 weeks after signing the seller passes away.

Hey Tanner,Welcome in, its a good idea to build your team as you get started and then being ready to pull the trigger when the right deal comes along.Our firm helps to track down unconventional financing for clients through various hard money/DSCR lenders.

Also, I'd like to know good lenders in that area. 

.- It's not lost on me that my parents acted as a lender, and that a lender would never pay someone's taxes.

I know a lender if you are in California. 

Did you work with any real estate professionals (agents, lenders, etc.) that you'd recommend to others?

Contact a lender and get pre-approved from them.

A lot of banks, credit lenders, and credit unions are offering ~5% on CD’s right now which is the best high yield I can find at the moment.

Hard money lenders and rehab loans do not exist here, though you can get some renovation funds together with your mortgage.REI meetups are more rare too, and mostly focused on investing abroad.
