I am looking to connect with new contractors working in any of the trades involved in typical SFH renovations. 

I have about 150k of cash capital to invest.My concern is an embarrassing one: I am a mental health therapist by trade.

Shares of single-family landlords Invitation Homes INVH -1.26%decrease; red down pointing triangle and American Homes 4 Rent AMH -1.65% decrease; are trading at 35% and 20% discounts to their net asset values, respectively, according to real-estate analytics firm Green Street. 

If you needed the money ASAP that won't be super beneficial. 

This would be the safest money but probably the costliest.Don't build a house of cards, Tyler.

So, if I withdraw $60K, about 75.24% of that should come from contributions (since that’s how my balance is structured).75.24% of $60K = $45,014 → Comes from contributions (no tax or penalty)22.38% of $60K = $13,428 → Comes from earnings (subject to taxes & penalty)Taxes & Penalty on the Earnings Portion ($13.4K)Federal Income Tax (24%) → $3,219Early Withdrawal Penalty (10%) → $1,342Total Tax & Penalty: $4,562Net Cash After Taxes and Penalty Fee: $55,437The DilemmaIf I leave the money in my Roth 401(k), continue contributing $525/month, and earn 8% annually, my balance could grow to:$229,865 in 10 years$606,905 in 20 yearsBut if I buy the property, it could generate $15.6K/year in pure cash flow, plus appreciation.

Just make sure you have your QI in place BEFORE you sell and never touch the money. 

I can't speak for this deal in particular, but you'll always pay more for turnkeys-- trade-off for not having to do any work.The only thing I see in the deal is Norada didn't include estimates for vacancy and repairs, and I would never analyze a deal without including those.

I can either purchase the land for 150K+ rehab cost with hard money lender.Or pay what they owe (50K) and get a construction loan and pay them after I refinanced the ARV.

These are usually very active, and I’ve seen a lot of volume traded.
