We are very new to the process but wanted to get into it because having a renter would allow us to supplement some extra income and help pay toward mortgage while my wife stays home with the young ones.We have inspection today and if all goes well, we'll be signing off with mortgage broker tonight.Our broker needs insurance information, but we don't quite know the best way to insure it knowing we will in the very near future rent out the basement.  

My wife and I are discussing buying our first rental property with the aspirations of having 3 or 4 to supplement our current income and hopefully fund college for our children which are still young.Our plan was to buy a home at 50-75k and rehab it with 20-25k and then rent it for 1-1.2k.

At the moment I'm looking to supplement my income.

I would ideally like to transition fully into real estate investing in the next year, possibly by supplementing with a few traditional real estate deals once I pass my real estate licensing exam and get sponsored by a broker.
