@Gaurav Chaudhari, only sign up with company that the has rating of A to A- (confirm the rating by googling the company) , also make sure to get dp3 coverage and replacement cost and not actual value.
I usually buy properties that are not making decent profit or none at all due to below market rents, most times TLC fixes this issue(Paint, light fixture, faucets). My rent are in the middle, not the lowest or highest this way my turnover is extremely low. Make sure to analyze the rental comps. I think Ben Mallah coined this phrase: Buy a crappy property in a good area, because you can always update the property but can't do much with the area.
Lot of people will offer you to buy into their system/turnkey, I am not a fan of this idea. I like doing my own due diligence and enjoy the challenge.
Finally I like some of the content from Clayton Morris has posted, especially on heloc, leveraging credit card.... I personally have done six figure rehab projects using my credit card with zero% interest. Do not buy into his program, he is getting sued for ripping of quite a few people. I think he is still selling turnkey properties.
