you know you get a good hail storm and the storm casher/roofers are out in force telling everyone insurance will replace your roof.. they cold call you..

Some people will push to get the maximum, even if it means they may wind up with nothing. 

Even for investors, this can be beneficial, as they avoid riskier commercial loans that often come with 25-year amortizations, balloon payments, and adjustable rates.Now, don’t get me wrong—buying more units often means more cash flow.

However since this is our first rental, we are getting cold feet and suspicion that it might be a money pit or go wrong drastically.

Every two years you have to get it tested.  

I have also read that most mortgages or liens get wiped away from a tax deed sale, except those that are through the municipality or county, is that true?

I seem to get this question, or some variation of it, fairly often. 

Hey Andre,There are multiple HELOC products out there which can close fast (within a week) & are not based on Tax Returns etc. and will still take income as long as your friends income is getting deposited into the Bank account. 

I'm looking to do what you have accomplished - get my first duplex and house hack it.

Plug in the town your property is in and get an idea of what other landlords are renting their properties for.https://www.furnishedfinder.com/?
