Im trying to work hard to get the credit the best i can like leasing a car and use a credit card.

If you are buying a home with an FHA loan and someone is already renting the home with a lease in place, then you are still obligated to move in according to the loan.

@Kyle Jones I've done 20% as long as it's currently leased.

However, when we asked the PMC to get them to sign the lease the tenant refused.

What are some specific structures regarding this built into a lease that may not otherwise be utilized regarding a traditional rental?  

I have a auto body shop that is located in a D class residential area, it was own by my grandfather, he is getting up in age and he is passing it to me. he hasn't done body work in years, he just have been renting the place out to some guys he know for like $220 a month. the utility are still in his name also. my whole idea is to come in, change things around, do the proper things, have a actually lease agreement written out for the tenants, with the new rate increase and rules, there wont be anymore of the late rent payments, there will be a late penalty, the utility will be in the tenants names,I plan to put a security system on the property, I'm new to all of this , its my first property I'm open to advice, suggestions, ideas on what I should do.

I've read the lease a couple times and it seems a seasoned investor wrote it because it includes a lot of the things I see over and over.

Then you back that money up with a breach of contract that protects that and even potentially charges more for violating the lease agreement. 

I am wanting to engage more frequently with people more knowledgeable and/or experienced than me.

I often have a new tenant signing a lease within 48 hours.
