If you discovered something, bring it up to the seller and ask for a credit/price reduction. 

I have the money for a downpayment and closing.I have 725 credit score The home would be a duplex.

I plan on using the rest of the equity in my first home as a line of credit to help fund a second rental in a BRRRR strategy or a flip.

I have pretty decent credit as well.

The liquidity is determined by the offered yield, and strength of the paper in multiple metrics (Seasoning, down payment, borrower credit, equity, etc).

If you are doing work for credit, you could pay dad back in maybe 5 years.

I recommend looking at several banks and credit unions in your area and asking them what there rates are.

The house is free and clear with just taxes, insurance and utilities to be carried until it sells so that is not a major roadblock.

besides money in your account, you can also use a line of credit such as heloc.A hml is not considered as cash.Since you're starting out, be very careful with auctions especially sheriff auctions.

I was approve for a streamline refinance that allowed me to lower my rate without checking my credit score.
