What makes a good home to actually make offer?

[Earl Louis]

i went out into the field used a rule of thumb. Saw a home that needed a lot of repair not good...so moved to another and saw for 150,000 used the 70% rule needed about 5000 in rehab. What would be good offer for home like this? Is a garage a must to be a good home. When I show analysis to fellow investors I want to make it look like its good but anyone help me out. Appreciate it...I'm not giving up!
