If there are any cards with less than ideal terms and conditions and that have a lower  availability then what is reasonably useful for your purposes, you may consider closing the accounts of those which are the youngest to at least boost your average age of credit by a little bit.

Ideally if I could get them all with one company on one policy it would be best, but the different States will probably prohibit that.

I deal with Sol Eisenberg and Gitty Loker.

I collect the fees in person when they give me their app, or online via Intuit's Payment Network.I get many people who whine about the $30 application fee, but my feeling is that if they probably aren't ideal tenants for me anyways.  

Ideally, your application (I just use standard Nolo) requires the amounts owed plus (this is KEY) the monthly payments.

I also want my first property to be a multi family ( ideally a fourplex), so thanks for making this topic.  

But only when you have found the ideal property.

If you needed to close the account to prevent partial payments, you would need to have a separate account for each property...For someone with more than 20 units, this may not be the ideal system.

Personally, I could stomach paying asking price for the property if Freddie was to credit say ~2000 for closing costs, but that would not be the ideal situation.Again any help is appreciated!

@Neelam KhanI would list the property for rent on the following platforms, put great pictures and mention the property closeness to the nearby commercial area but would refrain from mentioning that it is ideal for insurance agents.1.
