Sorry I can't give more but it is a fluid part of pricing.

Real estate is a very fluid field and has no set rules so that means you don't "need" conventional financing.

This is due to fact we are in a very fluid economic situation right now, uniquely fluid situation making predictability very difficult as we do not have historic data to accurately weigh from.

Kicking out the guys who make too much noise, dump fluids, park excess trucks, leave trash, empty beer bottles, yep. its a lot of fun!

How fluid is his deal flow?  

HELOC is best if you want to use the money more fluidly, and a fixed home equity loan if not.You could get about $80k using the home equity line of credit.

From experience I'm not convinced on the air purge method.Instead I use a 3/4 HP submersible pump in a 5 gallon bucket & pump fluid (usually the pink 'food grade' RV anti-freeze) through the lines.

As an investor or realtor, you need to be fluid and react to changing circumstances.

"I'm rebuilding the transmission."  

While shutting down some businesses and social distancing has no doubt reduced transmission, slowed the progression, and reduced the number of lives lost, the second and third order effects of all the shutdowns and isolation is taking many more lives from things such as suicide, drug overdose, alcohol abuse, delayed testing/treatment for other life-threatening conditions etc.
