Your insights can provide valuable context.Would you like more specific advice on any aspect of the appraisal process?

I’ve handled almost every aspect of renovations myself—plumbing, tiling, painting, drywall, and general construction.

Quote from @Nate Sanow: Yes I own two that are near 100 years old and I will tell you they are a pain in the you know what compared to all of my post WW2 properties especially post 1980… layouts are better in the last 50 years and energy efficiency is better and I can keep going… HOWEVER to reply to the other aspect of your question, I’ve found appreciation is better with older properties in areas of the path of progress.

What aspects of BRRR do you want to discuss?

What I love about Baselane is that it was built BY real estate investors FOR real estate investors so it's really dialed in to what you're going to need in order to prepare your taxes, keep your books up to date and the more operational aspects of being an REI like tenant vetting and processing rent payments.

There are several aspects of a long term lease that are not needed, or additions that should be included in a mid term.

But then their is the real world aspect and they just don't pan out.  

Besides the price point, there would certainly be a time savings aspect too (and we all know time is money).  

Besides putting together the best SOW using accurate/actual quotes as @Peter Mckernan and @Alan Asriants commented above, another key aspect is tracking expenses (bookkeeping) and monitoring the budget throughout the project. 

Regarding the Zelle versus Avail issue, I would advise choosing your battles wisely - as with many aspects of life.
