Every system you try will have flaws, or you may salivate over a feature that appears in other software.Some familiar names are mentioned frequently: Stessa, Apartments.com, RentRedi, TenantCloud, Innago, RentManager, Avail, Rentec Direct, Doorloop, etc.I recommend conducting thorough research on each app online to understand their offerings, pricing, etc.

I'd offer a discount for those who stay longer (eg weekly rate that is slightly less than 7 days). 

@Tim Silvers ask your title company if they offer an enhanced policy.

Over 10 is when you need to do a security offering of some type.

Is asking price * 70% - repairs = offer a good strategy?

Looking for some more experienced advice/perspective on a quadplex I want to make an offer on.

You can offer them cash for keys-give them money to move.

Also some lenders will offer this on newer originated loans.It’s not common but I have seen it offered on occasionIf there is a higher default interest rate then I would consider it but if it’s the same rate as default I would not accept it

do they then offer a  large  HELOC for the  full amount  ?   

Although we may see more inventory hit the market as people can escape "rate lock".I invest in today's market by searching hundreds of properties on the MLS, then going to see the top 10-20, then making an offer on the best at a price where I can cashflow after all expenses and putting 25% down.
