If they see the condition improving, they may well be happy to pay a bit more OR decide to move on their own.It won't necessarily be an easy process, but you have a lot of options.

I don't even have a credit card yet, but I probably should to start building credit.

If your biggest thing is safety, I'd talk with the neighbors, and tell them you'd like to build additional safety measures and improvements on the portion that's your land.      

Hi Guys,I've finally gotten my credit fixed.

Hi Mike, I am currently working with Evergreen Credit Union to obtain a few commercial loans.

The best I've gotten was 4.625% with a credit union for MF investment properties.

Has anyone heard of or have used Academy of business credit.

If you have access to cash, either your own, other's or credit, then you should be able to find people doing it that will partner with you.  

Better yet, there are a few lenders who will do "TBD Loan Commitments" which are having an underwriter approve your income, assets, and credit prior to having a ratified contract. 

For you first larger multi-family property, I would focus on areas that have proved to have rent stability, overall low capital improvement requirements, and a record of property appreciation over simply going for a property that gives you the largest forecast returns.
