I would anticipate it would depend on the level of detail you desired but it has been my experience that the will do free estimates.

My piece of advice would be to try to take advantage of as much free education as possible with podcasts, forums like these, YouTube, and other real estate investors.

@Jonathan Yake did you refi to free up your VA entitlement?

Also check if there are any boarding house regulations in your area that would impact you. 

Check with your broker for guidance.

Not in all cases but more often then not.Additionally you have to have solid management who is checking on the property at a minimum once per quarter as many times I find these tenant don't always report issues timely.  

While Treasuries are often viewed as "risk-free" investments, certain real estate deals in today’s market offer a compelling alternative—especially when purchased at a deep discount.Take, for example, a 1,000+ unit apartment complex in a suburb near Michigan.

Any advice/recommendation/similar experience is appreciated.Aloha Jinxiang,  I would check with your insurance carrier anyway before filing a claim.   

Mailchimp also I believe is free up to a specific number 

I would check with your insurance agent and the city.
