My core investing philosophy is pretty simple, and has done very well across almost two decades and numerous cities:1) Invest in cities with population (and job) growth2) Invest in parts of the city where household income is near the median (or slightly below)3) Invest in properties that provide cash flow from day 1 Thank you for sharing that. 

Hi Kendric, Ohio, and other midwest cities are good choices for low-price entry.

When wholesaling vacant residential land (city lots or larger residential parcel in rural areas) how long is the due diligence period?

I would like to think in a way that investment in general, and the real estate investment, start with a solid economic reason - "Why do you Invest, where you invested".To elaborate on below - Vegas is a great example where no real economic driver exists and when you invest there, you should be aware that is a highly volatile market (side note: i both 2 properties there in 2011 and 2012 and i sold both this year) and you should pay an extra attention and be prepare to reposition capital.It's clear, if you invest in Vegas or Orlando (just 2x entertainment cities) you will expect ups and downs and you need to position yourself with extra reserves and extra caution if you are planning to stay in these market for long term. 

At the time, we were not thinking as investors and primarily focused on buying a modern, pretty property under $1M.

But since that time I left my corporate job, moved states, my daughter was born and is now 6 months old, and I began investing in a new city.

It is a 3 unit airbnb portfolio with each unit in a different city.

I'm based on the west side of the Twin Cities and am investing on MN's North Shore (Duluth, Two Harbors, Grand Marais) The house were under contract for is a long-term duplex. 

Now that people are starting to socialize again and this city is opening back up soon, I would imagine that many renters and visitors will be coming back to SF in the next year or two.

Remind them of quiet hours, city ordinance, right to quiet enjoyment, etc.
