Your father must be proud of what you have accomplished so far, and the progress you will likely make going forward.I would suggest, before jumping into something, going to a couple of Real Estate meetings near you.

I have had enough of him, his attitude, his excuses and his lack of progress. 

We put in curtain rods for most windows, and cellular shades when the window location requires more privacy (bedrooms, busy streets, etc).  

The whole picture matters, so this may or may not impede your progress, but based on your post it could possibly be quite the hurdle unfortunately.

My plan is to progress further using the BRRRR strategy and finance the initial buy and rehab with cash from HELOC's borrowed from relatives.

For what I pay him, he will show me lots of houses, meet with contractors to get bids and even check on the progress of repairs in a pinch.

the other place were I have seen fortunes made in real estate is in Timber and in path of progress farmer bought the dirt outside of town town expands  DR Horton pays 10 mil for their farm..I see those.. but someone who is staking rentals with only 20 or 25% equity and making a 100 a month or 200 month.. while I have clients that do well. make 20 to 30k a month and live a nice lifestyle .. they are not in the same league and they work their but off for it.

One thing you can do to speed up your progress towards a 6-figure salary by age 30 is to not only house hack the 2-3 unit, but also BRRRR it.

Good luck with you real estate investing journey and keep us posted on your progress!
