Where to get the most recent and accurate data for things like:Unemployment dataPopulation growthJob diversity and top employers in the areaVacancy rates (eg huduser.org)Property taxes and jnsurance costsI saw bp pro and reventure and a bunch of other websites provide some of this data, but i wonder how accurate and recent it is.

Hello Frank, I think house hacking a small multifamily property that you buy with a low downpayment is one o the best and lowest risk strategies that you can get started with.

I also know that I can get HELOC on rental but I wanted to find out if any lender will give HELOC on a rental which is owned by LLC. 

I provided a free rent back for 2 weeks so the seller could get her funds and relocate.

One of my applicants showed up with little credit but no defaults, no evictions, and only traffic violations and verified income high enough to cover well over 3 times the rent and I accepted the tenant despite there being some signs.He paid the rent in time for the most part until a few weeks ago when he stopped and I could not get ahold of him.

They were pretty regular in getting deals and the properties were not horrible. 

Quote from @Laura Yelin: Hello BP'sI like Sherman...I lived there for about 3 years many years ago and still sell and rent there.It's a slow wealth building market in my opinion, not get rich quick.Mostly blue collar stable town.

The refund part is just to get you get committed to another deal that makes them even more  money than that refund.

First thing I'd do is check comps to get an idea of the demand and rates you can charge for your condo as a MTR.

Please update us with what rates you end up getting quoted.
