Congratulations Angel, home ownership is the pillar to building wealth in my opinion.Continue building equity, buying rentals and before you know it, you wont believe how far you've gotten.

Got $100k business line of credit with 710 credit score to buy some more properties.Do you think it is better idea to buy a rental house (worth $70k) with the credit card paying all?

An experienced investor will never buy in NJ without seeing inside or they'll really low ball you.

What we've done is use the BRRRR (Buy, Rehab, Rent, Refinance, Repeat) method.

I wouldn't want to buy in a high crime rate, especially violent crime, area, but what percent is worth my time and money?

I agree with @Ned and @Chris   also don't fall for buying any monthly software subscription.   

Did you buy your primary home plus house hacking it?

I've been buying and selling MF in Vermont for 10 years. 

If you can buy and hold, you will make money in the next 3-5 years, even though you may have a temporary negative equity experence. 

The third pic is ten percent down with us us buying the rate down to 4.5 percent.
