My day job is a home inspector so I see a lot of properties and know a lot of the issues that I will typically find in different homes based on their age, style, location, ect.

The positives are the attractive city location within a big, growing population...in a city with strong job growth within the health and education sectors, among other big employers. 

The rest of the money is used as operating expenses and to grow the business.

I am looking to grow my portfolio but I have no idea where to start.

This is the same reference to "cycles" that @J Scott has popularized on BP.com.It shows (though with a time-lag - this is 2018) which areas are growing and which are overheated for multifamily, in which cities. 

I've looked at the demographics for statistics such as income, population age, resale, new development, taxes, economic growth potential and with a few variances which appear to be associated with the size of each area, they seem fairly similar.

What is your experience with handwritten letters vs typed, printed and signed.I currently have a couple small multi family properties and have realized ater listening to a recent episode that if I want to grow my business I need to get into direct mail and create opportunites rather than waiting for them on the mls to pop up.

Now we are realy looking to scale and are in search of an investor/partner to continue growing. 

I Have a W-2 job that I absolutely love and have no desire to leave for about 20 more years, which will put me at age 51.

It’s a once in a lifetime opportunity for me and I want to make my folks proud of what I do with it and grow it into something wonderful to leave my kids someday.
