Also finding replacement parts can be a challenge when you need them right away. 

It merely escalates on return engagements.

Could anyone share a few of those experiences and tell about some of the challenges that they may have had and what methods they used more than once?

A deal of this size requires engaging 2 people: an accountant and an attorney.

I can definitely see the challenges with owning multiple doors out of state.  

Here is my challenge to you, take the safe goals that make you feel comfortable and throw them in the garbage never look at them again.

Nowadays I have a roster of probably 30 vendors that I can reach out to (and sometimes I blast through all my options for a particular problem).The biggest challenge is find good handymen for doing low hanging fruit (fix outlets, fix sink, change light fixture, spackle/paint).

Thus, those who engage in these activities should get a tax break on related expenses.

@Alexander Nason - it may also be worthwhile looking at a Fannie Mae Homestyle Renovation mortgage: https://www.fanniemae.com/content/fact_sheet/homes...Homestyle loans require a higher down payment for 2-4units and loan limits aren't as high as FHA in some areas, but I think this could be a better option long term if you can figure out the remaining down payment:No upfront mortgage insurance premium (1.75% on FHA)Cancelable mortgage insurance (once you reach 22% equity) We bought our 4-plex with an FHA loan and it has been incredible - 3.25% interest rate and 3.5% down on $700k would be really challenging outside of FHA, but my mortgage insurance is almost $600/mo. 

Implementing it over the course of time through a set of daily rituals is the challenging part.My strategy in a nut shell is:Mind Mapping the flowCreate a Massive Action PlanDevelop my identityBuild my brandSeller outreach using an outreach matrix and tracking resultsAttending conferencesBe in a position to close when the opportunity presents itselfWhat is your strategy or how does it differ from mine?
