Sit down with your partner and sketch out a plan of what you want to accomplish in the "now", the "mid term" and "in your dream scenario", then earmark several hundred dollars for professional fees and find yourself an attorney and accountant with cross-border business and real-estate experience (interview these folks like you would any other professional on your team until you find people with whom you are comfortable) and come-up with a starting point and a plan for growth which will allow you to add organisation as needed w/o incurring a large taxation event.   

I have earmarked, put in notes and tabbed pages, I have not done that much in book note taking since law school.  

Many contractors cut their teeth by floating one job by paying for that job with money ear marked for another job, planning on using the final payment from the finished project to go into paying for the project the money was originally ear marked for. 

Put the cash in a separate account that is earmarked for investment only.

Now I alway maintain at least 6 months of PITI + max insurance deductible in addition to any funds earmarked for CapEx.

Our partner already has the funds earmarked for another. 

We could pull that out of an account earmarked for the next investment property (house hack #2), but I've heard people say that they often get a HELOC on properties, so they can tap into the HELOC for any future purposes (say, updates to the next investment property).

If they are low budget suggest to them to look into having a banner made and hanging that (if the city allows) if not an awing sign might work.If your lease addresses signage follow that--it if doesn't I think you may have to rely on renter good will.If the city controls signage, length of time before a proper sign must go up, that should be followed, but again (I think) your lease controls.Signage is expensive, electricity to light it is expensive, renter may not have very deep pockets with respect to cash right now--or have the money earmarked for some other type advertising such as email blasts or etc..Maybe they have game plan to get signage when they reach X dollars of volume or X amount of cash in the bank--signage and installation is expensive.Good Luck!

I have an high stable Salary/Bonus income stream and $50k earmarked to start developing a portfolio of income producing Build-for-Rent properties.

I can't do a 1031 because the cash from this property is earmarked for another property that has to be done in cash.
