If finding a new replacement is more difficult then get your new property under contract first even before your old property closes.  

In our experience, the #1 mistake landlords make when selecting a Property Management Company (PMC) is ASSUMING instead of CONFIRMING.

The approach involves using a hard money lender (HML) to fund 75% of the purchase price while having the seller carry back 25% in a second-position loan, allowing you to flip the property with little money down.

You got the lower down because the property is owner-occupied.

I just wanted to get into real estate investing and this property was in great area.

Do the math and see if an ADU is worth the cost and effort.https://www.biggerpockets.com/blog/rental-property-cash-flow... 

Unfortunately each one is worth 25k. thank you  traditional lenders are not going to finance these properties.

However, an easier option would be to use a bridge loan to help with acquisition and rehab financing if the property needs some work.

Quote from @Dylan Webb: Hello, here's my situation:My wife and I own several properties separately.2 of the single family homes combined we have conservatively $150,000 in equity ($90,000, $60,000) I want to use one of these as collateral for a small loan of $30,000 to put down on a high cash flowing property OR have a lender finance the whole venture at a purchase price of $160,000.

I used to work in finance and we could get clients approved for a HELOC in less than 24 hours which will be much quicker than the cash out finance.
