I know it is hard but over time, through repetition, you will become an expert at a quick NO or determining how to move forward. 

It should only take you about a month or two to contact everyone on your list and then the tough part – you start all over again.Why the repetition?

The key to establishing a solid track record is repetition.

if you see a house about to be rehabbed, chances are that investor does repetitive moves and has a regular team.go in the house and get the contractor name and contact info (just be sure the flipper is not there) and/or write down the name of the licensed guys listed on the permits. call the village & ask for their contact info or just googled it.if the permit is a GC or construction company, don't even bother - they just farm it out or have employees.

Not mentioned in first post, but getting the scoop on tenant came over the course of multiple interactions - that were strangely repetitive and rambling at times... and he has since called back and left messages wanting to talk about it some more - that the rent was often late over the last year- why the glowing rec then??

@Mauricio Lopez this is a tough noise complaint, I have lived with the noise of an autistic child and know it can be loud, repetitive, and grating.

So, you can make money and learn invaluable lessons with a HH, but it's typically a much lower risk strategy than BRRR'ing, flipping or wholesaling--which are strategies that (when executed poorly) can easily bankrupt a beginner.Moreover, house hacking can be very lucrative, and there are multi-millionaires who built their fortunes on repetitive house hacking.Now, having said all that, house hacking isn't necessarily easy (if it were, everyone would do it)...it's just easier than the more advanced strategies...House hacking still takes significant due diligence, skill in analyzing the market and the property, time and effort to learn about tenant screening and property management, the ability to anticipate appreciation/depreciation trends, etc., etc., etc....and even with lots of skill and preparation, things will still go wrong (vacancy, plumbing leaks, bad tenants, etc.)

I'm no marketing expert, but I think the success of that would depend heavily on repetition, which would get expensive. 

This does seem like something that comes through repetition and experience.
