Same goes for social media presence. 

But why would I do that if their presence help me to get two more months rent that I wouldn't have.

The housing market is currently very healthy and we have no reason to expect a housing crash even in the presence of an economic recession, so for those reasons I believe it is a great time to buy.

You are operating a business and you always need to keep in mind that what tenants say and do comes with the territory. 

If this is strange territory or confusing I would consider interviewing a few CPAs/EAs going forward.

Plus when they did receive your letters you are an unknown in the marketplace, so motivated sellers are unlikely to deal with you when they can deal with a more familiar presence in the market.What I would do if I were you is keep looking at the MLS and comparing prices.

These are the first tenants we've ever had (they've been there for 5 years) and so this is uncharted territory.

If you do not know how to screen properly you are entering into very dangerious territory.

  #2 is that as soon as you turn your primary residence into something else, like a rental, you are now entering the territories of losing your $500k Sec. 121 exclusion (MFJ).... of which there are variations based on timing and circumstances.#3 is, if it's just for liability protection, why not get an umbrella policy? 

So I’d look at all the major cap ex items you’ll potentially need to address in the next few years and make sure your gross capex allocation is enough to maintain the property without dipping in to the $2,400/yr. cash flow, which isn’t a very wide margin before you are getting into negative CF territory.
