Quote from @Milena Garcia: this sale I hope is all done after 2 months..

Purchase price: $136,000 Cash invested: $90,000 Sale price: $260,000 full renovation from studs What made you interested in investing in this type of deal?

DSCR Loans - Both Purchase and Cash Out Loans- Investors typically use these on the cash out portion of the BRRRR Strategy - Minimum Downpayment, usually 20% but some lenders offer 15% down - Max LTV on Refinances, typically 75%, but some lenders will do 80% - Minimum Title seasoning (since the property was purchased and recorded on county records) is 90 days, although some lenders have no seasoning at all as long as you can show rehab work completed. - 30 year fixed terms - Usually have a Prepayment Penalty from 1-5 years, although you can price out a 0 PPP for a higher rate or fee- Minimum Credit score is 650 usually, although you could do a lower LTV loan at 620. 

I’d simply ask in what situations where the broker and the brokers firm did nothing to facilitate the sale do you think you should get paid a commission?

They are two separate sales agreements. 

If not then sale.  

Getting a bit overwhelmed with all the required County Level and City Level business licenses, STR permits and Tax accounts (Business Tax, Franchise & Excise Tax, Sales & Use Tax) to register with the state.

You'd think 60 years would have cleansed all that but it hasn't.You might target social service and local agencies since this property was in the past a half way house or similar and was only converted to market housing to make the sale to you.

The building is now vacant in the bottom portion including by sister's business.

What is more common is someone saying they have everything, calling it "easy" and it's all just BS sales pitch.
