I'm dealing with a 70-year-old owner who has spent decades spending every bit of her monthly cashflow.

But be carefull , again,  they are dificult to finance or obtain a loan , usually private loans are more expensive and they have higher interest rates . hope this help!

Even if I have to wait 6 months and spend $50K on a different buildout, I'm still doing better by month 15. - I believe that companies and the economy as a whole have begun a long-term shift towards back to in-office.

In fact, I would bet that 99.9% of all wholesalers could spend the some number of hours working at McDonalds and they would make more money.I recommend you focus on the house hack.

Until you spend 20k on paint and some new kitchen appliances, but the roof and foundation are still shot and the 100k ARV is more like 70k in reality.

I was able to lock in private money to purchase the first of the two properties with plans of doing a BRRRR.

And thankfully, by the time I needed to execute on those options and actually complete the purchase of the leased properties, I had developed some private lender relationships that allowed me to complete those 3 transactions and several more thereafter.

FB is not my fav, they are neither professional nor private. 

Securing loans with a low credit score is possible through private or HM lenders.

If you have the time and want to spend the effort then doing it yourself is the way to go.
