Honestly it’s all about opportunity cost.If that additional cost is going to yield you more than it costs; then pull the trigger .If you borrow a down payment, it’s going to reduce your cash on cash return as your mortgage payment is increased. 

They claim returns that would make any investor salivate, but market towards new investors with small investments required ($50k for instance).

I guess you'll have to ask yourself, do you want to be a return on equity, or a return on cash flow investor. - Ideally you want both but with a lower down payment, the less cash flow you have due to high mortgage.

@Brody VeilleuxTo maximize returns on multifamily housing, focus on mid-grade updates, amenities, curb appeal, utilities, exploring additional units, creating flexible spaces, and refinancing with a value-add record.

In Michigan, and much of this probably also logically applies to Ohio, a DEPOSIT must be returned. 

In return, our partners are highly engaged and bring us their best ideas and deals.In our first year of business, Mindful Real Estate Partners has two GUC exits, another two under contract, and 15 active deals.

Thanks @Bob MaleckiSo by return are we talking about annual return? 

I don't know if the returns would be there unless you are doing something at a scale where you have half a dozen to a dozen STRs in the same general proximity. 

If the sale goes through, we are making a substantial return (hundreds of thousands of dollars).My spouse and I want the money now and want to avoid the wait and see.

I like NV.It sounds like you’re all about keeping things short-term and maximizing returns with each flip—property taxes aren’t a concern when the hold period is brief!
