Not sure if you're aware but, nowadays, Google Translate translates any web page so there shouldn't be any language issue on these sites for non-Spanish speakers.

At RAD Diversified, we offer investment partners the opportunity to invest in income-producing farms and cash-flowing properties like residential & multi-family with substantial value-add opportunities. 

if you are going to add value and cashflow the Laundromat, I'd assume that having the business produce the funds from profit to pay off the owner's note would be somewhat straight forward.If the deal makes sense and the cashflow is there I'd think a cary back would be a good way for the seller to get the number they want and for you to bring little or no downpayment.

We put an emphasis on vacant prospects, those with separate meters and realistic balance sheets which when combined with the right financing terms and management can still produce a healthy and safe addition or anchor to a portfolio. 

If your target demographic (upper middle class/upper class/government workers) for your STRs are less impacted by these factors then that market will produce a better return now.7.

Multifamily real estate investments, such as duplexes, triplexes, or fourplexes, have the potential to increase total cash flow as they may produce several sources of rental revenue from a single asset.

Introducing a fair negotiation on terms with (1) end price, (2) length of term and (3) cash up front could likely produce the results you BOTH are looking for.
