Before I was born, he used to buy cars that needed work (brakes, tune up, paint, etc.) out of the classifieds. 

Tough and not fluid.

I used lighter fluid to clean the grease off the sides of the stove and used lighter fluid to clean the grease off the kitchen cabinets and stove hood and fan.

If the belt brakes your pants will stay up given the braces (suspenders is the US term).Your model and your assumptions are not facts.

Better to keep your cash fluid then to buy into a bad or marginal deal and have debt you can't get rid of .Not only then are you getting little to no return but now you have debt that affects your ability to buy the great properties when they come along.If you wait all year and just buy 2 properties over 12 months but are winners that is better than accelerating to buy just to buy and you have 6 properties ( 2 losers, 2 marginal, and 2 that do well).

@Harsh Singh its all about not paying to much and building a margin there that if you have some vacancies the property will still cash flow or brake even.

Only because, those numbers are very fluid, they will change, depending on the overall acquisition price. 

Bottom line, it's way easier doing it with an experienced investor, no sense re-inventing the wheel.FlexibilityNo two markets are alike and real estate investing needs to be fluid.

You want to be sure you engage each person as a fluid conversation while keeping the items that you need to gather in mind.  

Give me a brake.
