For me, the key to asset allocation is alignment with my goals in life (my "Big Rocks") - check out 7 Habits of Highly Effective People, changed my life 3 years ago. 

Also keep in mind that for those that are partially renovated means you could allocate that money towards the down payment to make it more affordable on a month-to-month basis.

Like him, I have many interests and a good work ethic, but can't allocate the time due to my W2 job.

For me on the commercial side I have to allocate time to only serious buyers and sellers.

Just make the correct allocation between the primary residence (§121) and the rental portion (§1031)."

I am just now starting to allocate about 10% of my funds back into marketing and advertising and growing my company sending out mailers and doing door knockers.

Sharpen your pencil to get actual expenses (HOA, insurance, taxes, management (even your time), allocations for CapEx (appliances), Repairs, Rent Ready, etc.) remember your taxes would be jacked up based on the new purchase price.  

If you put down 20%, that's about $50/month in cash flow (depending on how much you allocate for taxes, vacancy, capex, etc...) which isn't a whole lot.  

Unfortunately, I don't have a lot of funds to allocate to my mailings just yet, so I can only do a small batch maybe 100 at a time.  

We also allocate a capital reserve out of Net Income (5 - 10% depending upon the age of the property and its systems) to address things like a new roof, new HVAC, etc.Capital improvements are a given in this business, so best to budget for them ...
