@V.G Jason No amount of market knowledge or expertise can insulate your business from external events outside of your control. 

Here are some stats:'The Association of Real Estate License Law Officials (ARELLO)(link is external) estimates that there are over 3 million active real estate licensees in the United States.""

Pressure washing allows you to measure how many homes you've serviced, how much external square footage has been cleaned, and even scale up to a team if needed.

I found a property that’s tied up with a law office, the city and the county for taxes going all the way back to 2012.It’s been condemned as it hasn’t been maintained externally and was considered abandoned.

I have been doing a house hack the last few months of my 5 bedroom SFH (have filled 4 of the rooms and I live in 1 of them) and am now renting an external garage here for someone with an antique car.

While most flipper would give advice on the technicality, i would say flip reward/risk is created when you purchase and the future market trajectory based on external factor, such as inventory and/or future interest rate movement. 

There are too many external forces right now to guess what will happen - what will fed do, what will congress do, what will happen globally.

When the buyers scatter, you need to look at external factors as well. 

It’s an negative externality aside for maintaining the property.

OR you have to order 'retro-fir' windows that have external fins...they slide into the opening from the outside, but they are a custom fit - add $300-400 per opening and 5-6 weeks to your time table....but then no exterior trim and a little on the inside...
