Duplex's or MFH properties can have 4 unrelated per unit by default.

(Lenders will use Market rent by default if there is a mid term rental). 

I wish I knew, but we're talking about prepayments prior to a reservation.Previously, I just let the OTAs set their default (Airbnb 100% & VRBO 50/50), but now that I'm paying more attention to it through Lodgify, I'm going to do a 50/50 split and see if that helps increase bookings.

They could get a risk free return by investing in T-bills, so the delta between that RFR and what you're offering needs to be rewarding enough for them to pursue it.As for the 2nd part of your question, that really is a mystery :)The low interest rate environment always leads to these folks misleading people and mismatching deal operations, and sometimes even defaulting on the property and losing it altogether.Probably because a bunch of these syndicators want to be cool Instagram/TikTok influencers and throw up their arms and talk about how many doors they own, but what do I know lol. 

If it is a fixed rate loan, I don't see how they can increase the rate if you are not defaulting - but your mortgage / loan agreement should spell things out for you.   

She couldn't understand why she didn't get notice about the actual auction sale....and I said "You did, you got foreclosure notices, and once they issued a default judgement, the County doesn't care anymore." 

If they default, I just sell it again!

An example problem statement that I may have stated (and built the software for) in 2003, when I started investing full time: Build a tool for lead generation that collects county records from the county recorder's office (and property card data), finds the recent first mortgage defaults  from trustees websites or public filings for properties that are between 1000 and 1700 square feet, in a neighborhood of 90% like-kind properties with greater than 20 parcels, houses built after 1978, that can cash flow at current rates when fully leveraged. 

My main concerns would be:- corruption- collecting rent (what to do when tenants default?)

NOW you have time to refinance after the loan is not in default anymore.
