This can vary by state law and I don't know the specifics in Arkansas

I had a co-worker who would get a home warranty like American Home Shield etc and put hose on each of his rentals.  

But ,no pun intended, they HAD to pass a Texan law to limit you to 6 sex toys.  

I recently purchased my 2nd townhouse for my in laws (paid $180k cash) but I plan on refinancing and having a $80k mortgage(15 years).

It appears you do not live in the United States, so my advice is based on US law and might not be helpful. 

Getting paid on the 5th or 6th sucks, but if I had tenants who were otherwise great, I'd deal with that.You might run into fair housing law issues if you try to charge them more because they have kids. 

First step is to learn the laws pertaining to solicitations to the public, including internet forums, to potential borrowers or investors.

It's complex and there are about 3100 taxing units (counties) in the US, all with their own set of laws, rates and auction styles and rules. 

My experience with property managers was one that would quickly put the small guy out of business.I spend a considerable amount of time and money staying educated because the tenant/ landlord laws are a land mine for unsuspecting and uninformed small landlords.

I am also not sure what laws fall into play here.
