Daniel, It is totally Possible.
I partnered up with a co worker. we both wanted to look into real estate investing Buy and holds. we started buying hud properties as investors. As an investor you get what's left after the owner occupants. usually the ones that need more extensive rehabbing. We do most of our own work. with the exception of HVAC, Major Plumbing, roofing, major electrical. WE know when to call in somebody.
Our philosophy has been , good roof, good floor, We can handle about anything else. If we can get a good 1/2 day in that's a great day. Our rehabs took a little longer in the beginning, Now we can get them mostly done in 30 to 45 days. we have done about 50 Houses now (SFR). We are currently holding I think 44 today. Our coverage span is about 200 miles, and we work on the farther ones on weekends. We have been doing this about 10 years now.
The rest of the story, our w2 job provides:
The Good:
Health Insurance, (im in my mid-late 50's)
paychecks, more money to invest, and pays my bills.
Paid vacations.
The banks love the fact that we don't need the money from the rentals we reinvest about everything to pay off sooner.
No employees, no workers comps, no one else tearing up my trucks and no one stealing or pawning my tools.
The bad:
meeting city officials after hours and utility company's is very hard to do. usually involves a vacation day from work.
extended holding costs just takes longer to finish the rehab.
End up hiring more contractors to finish some things I could have done myself.
The hardest thing I have to do is keep reminding myself it's a rental. it doesn't have to be perfect. If it's a flip, that's a different story, nicer floors, ceiling fans, window treatments, etc.
