(If radon is an issue and you know about it as others have stated the cost to mitigate has gone down significantly and I’d do so).

Before submitting an offer, contact the Condo association to understand whether the property is non-warrantable (will require Non-QM financing) or warrantable (Approved by Fannie/Freddie) as that will impact the rates and terms you’ll qualify for  Lenders consider all costs when calculating your DSCR so get a head start by asking the association for HOA fees as this can really impact your ratio.

EDUCATE YOURSELF - yes, it will take time, but will lead to a selection that better meets your expectations & avoids potentially costly surprises!

I've had bad experiences with two different property management companies in Columbus that stemmed from them not taking timely action on repairs that cost me a lot of money and also not identifying obvious things in inspections that led to higher turnover rates and increased the time that it took to get the unit ready for the next tenant. 

Example:Mortgage approval up to $600k20% down payment = $120kClosing costs = approx 1.5% $18,000Furniture costs approx $30,000 based on $20 per footv at 1500 sqft homeMoney partner agrees to contribute all necessary cash approx $168,000 to purchase and set up STR. 

Vacancy/turnover is very costly.

There is more upfront cost, but if your vacancy is low, then you can have significantly more income over time. 

What are other questions we should discuss in advance.any advise, any sample document.Thanks look at 10 joint venture deals before you do one. talk to others in other markets. if he isn't smart enough to negotiate capital or JV deals or structured finance I wouldn't touch him. every cost should be fully transparent with their margin. similar structures with investors in columbus we are the general and everything is negotiable. he should also be qualified talk to a bank first. we take title in a single purpose entity we are the LP less than 20% and the qualifier and the main investor puts the cash and gets the loan, I'm also licensed and normally sell to out of state investors. 

I need $33,500-$40,000 to complete the rehab including cost of permits, labor, and materials.

Another investor of ours wanted to grow their portfolio and their goal was to diversify out of the west cost.
