Although it's a strategy that's good for beginners, there are plenty of very experienced RE investors who continue to HH.Plus, if you do decide to do one of the other strategies in the future (such as out of state investing), you'll be much more prepared to do it if you have a HH or two under your belt--a ton of the lessons you'll learn from a HH can be used to successfully execute an out of state investment/BRRR/etc.!

Probably at least 20% or more, this will help cover the unknowns and inflation.The contractor may charge you to prepare an estimate, however look at cost of the estimate like an insurance policy.
