That would be called the BRRRR strategy - there is endless info on that strategy here and on the podcasts and in the BP bookstore.

Let them move in with a deposit and first months rent. 

Separate accounts per property incurs a lot of overhead, such as minimum balances or fees for missing the minimum.I use separate accounts for each tenant's security deposits.

The numbers no longer look nearly as good on these investments (now more like speculation) and I will now be forced to get my deposit back or accept this new price.

I would keep the deposit unless I am able to rebook the dates and then I would only make her pay the difference for any unbooked nights. 

Property manager (PM) 's lawyer continued the case to get the unpaid rent from the tenant.PMA between landlord and property manager(PM) has also expired so landlord got the property back , but when landlord requested to settle the account and the deposit( there is one month deposit from landlord also), PM refuses since the lawsuit is going on with the tenant, Additionally PM is still charging the monthly property management fees from landlord even though landlord is managing the property.Landlord is done dealing with PM and requested the PM to withdraw the lawsuit against the tenant ( landlord is aware that he will loose 2 months rent), PM came back saying they cannot withdraw the lawsuit since that will violate fair housing law.QUESTION:Does withdrawing unpaid rent case against the tenant violate fair housing law ?

Just participated in their webinar, which wasn't live, but just a video at the end when he was showing testimony, he said that guy make a first deal with paying EARNEST Money DEPOSIT with his OWN money!!! 

You could put a small deposit instead of 20% on a loan.  

Quote from @Havital Miltz: I think it will be very difficult to show 750 hours, most tenants deposit the rent, so there is no rent collection. unless you have a very high turnover of tenants, where  you need to show the houses again and again,  I am not sure where you can "find" all those hours for her, especially that you say the properties are newer, so how much repairs would you have?

The vast majority of lawsuits against Landlords are for wrongful eviction, security deposit disputes, and Fair Housing Violations.
