It's been 5 years now in the biz, and we are pretty busy that I'm having a terrible time doing the "home office" thing anymore, and would rather get an office/warehouse n put someone there for the phones...
Congratulations on being busy, Bill. And
your dilemma is a common one among our SFS graduates.
Remember that the rent on an outside location is just the tip of the iceberg. Plus even more than the increased overhead you should realize a retail, high-visibility location is an entirely different business model.
For example, I assume the reason you want high visibility is for the "drop in" traffic which is great. BUT it is a negative Moment of Truth if your prospect parks, walks up to your front door eager to book a cleaning job and ... NO ONE IS THERE. So now you need it staffed full time. (this isn't as big of an issue with an industrial warehouse location.)
We moved out of our house for the exact same reasons. (Plus too many techs there every morning checking out my wife in her robe, etc.) There is a time. But it IS a totally different and potentially more constricting business model until you get up to "Critical Mass."

PS I wouldn't count on your landlord's business. Do the deal if it makes sense without the work and view it as a nice bonus IF it happens.
