For us we all typically use 0% business credit cards to furnish the property which can amount to $40-$60k+ depending on how crazy you go. 

Have about 50k I would invest (access to more), with excellent credit and good income too, from my full time job.

I looked around and found lenders that will do a day out of foreclosure up to 50%LTV down to a 500 credit score but the loan amount minimum must be 300k.

@Jonathan Small government actions have led to an unprecedented 40% increase in the money supply, 50-year record inflation, record increase in interest rates, bank failures, credit tightening, CRE recession, housing affordability issues, mobility issues, inventory issues, and massive impacts to the world economies, every investment class, and our families, kids, and friends like never before. 

What documents do they require, what credit scores do they allow, how do they verify previous rental history, etc.?

I do not use a property management service to advertise and have always used Zillow to advertise, previous references, housing records, credit checks etc

Use services that can validate the authenticity of documents and employment history.Require Detailed Applications: Ensure that the rental application captures comprehensive information, making it harder for fraudulent applicants to provide fake details.Conduct In-Person Interviews: Meeting applicants in person can provide additional insights into the authenticity of their application and allows you to ask follow-up questions based on the details they've provided.Utilize Professional Screening Services: Professional tenant screening services are invaluable for conducting background checks, credit checks, and criminal history checks.

My first ad budget was $295.00 credit I got from my local news paper. 

For me, I am a little hesitant because I would be in a situation where I would be trying to secure traditional lending (which should be very feasible given credit scores & what $$ amount I am pre-approved up to from my banks), meaning that I assume I would be forced into using my first-time homebuyer loan incentives.
