My top recommendation is to begin by contacting property management companies in each target area.

I'm still in the process of growing my portfolio, but have heard others 1031 all their smaller properties into a larger building and have a property management company manage, OR, set up a seller financing deal with another buyer that gives you the cash flow you desire. 

I run Blaze Real Estate a property management company in Amarillo.

Where these numbers are found, there is a very high rate of rent actually being paid.We have over a dozen Fortune 500 companies just in Metro Detroit with huge Healthcare, Auto, and mortgage industry National footprints.

I would look at buying 5 properties using loans that have some sort of value add aspect in a market that I believe will appreciate at the minimum of the historic national average.This may be a rather boring and unflashy answer but I believe it would be the best money spent in my current knowledge and expertise.  

OPIf you have a company with a Sales tax license.  

Now he has sold the company and is more of a flat rate charge based loosely on how long it takes him to prepare the return.

As an Airbnb shareholder from IPO I like what they do hiring third world reps to handle issues, but as a PM company owner and STR owner I despise it. 

SW MN is hard to find Landlord Insurance, all local insurance companies say thy quote you landlord insurance, but they realy quote you general home owners insurance.

Call some local HVAC/Mechanical companies and ask what the average cost would be for this upgrade!
