I am seeing more and more investors having difficulty selling their property and refinancing them since they are highly over leveraged. 

So, if you are buying in lower end areas or an area that is harder to attract high quality tenants, you will likely have more vacancy due to fewer qualified applicants and often time wear and tear that can be fairly expensive with each new tenant.

High prices + high mortgage rates + low inventory is making this a challenge.

They took almost a year to rehab it and it's been sitting on the market at a high price since then.

The challenges include - Interest rates - that are as high as they have been in 20 years; property values - which have doubled and tripled in the past 3-5 years.  

I was using PayPal, cause instant and no bounce but really high fees

For instance, I thought some of the purchase price for the properties were way too high above retail, or the rehabs weren’t very nice and didn’t looked rehab at all, or they were renting at well below the 1% rule etc.I took a look through Antoine's inventory and found the purchase price of their homes were in my sweet spot: $60-100k in markets like Cleveland, Memphis, and Birmingham.

The wholesaler had it priced too high as he used comps from March.

There are markets that are very saturated with STR and with vry bloated prices and high interest rates it could be impossible to turn a profit at all. 

I aim to refinance the loan under conventional investment terms to avoid the high interest rates associated with hard money loans.With an excellent credit score, securing a loan shouldn't be a challenge.
