With actual cash, you just transfer it. yes, but you can still bid with lender approval - without appraisal contingency - you send in deal (app), it gets approved by lender its functionally the same as cash (except in true lightning speed situations where there is a quick auction with little time to prep but thats generally pretty rare I'd think)Right, but that's not cash or functionally the same as cash because the lender can change the terms at the last minute, as often happens with less experienced hard money lenders.

Get a lot of rentals first then worry about it at a later date.

You could have those dates booked on Vrbo instead if the dates were open and your ranking on your main platform would be higher which led to more exposure. 99% times, getting a higher ranking on one platform worth way more than picking up a few bookings unless a few bookings are what you are looking for.

If you submitted an itemized breakdown within 30 days of your move-out date, there should be no issues.Did you take any photos for your records?

I would be surprised if there weren't notices given to both the defaulting End Buyer (You're in default, you must close by X date or we're forfeiting your deposit) as well as the escrow agent (Buyer defaulted, see contract Earnest Money paragraph regarding release) prior to that actually occurring.

I suspect the person who originally turned it into a fiveplex only applied for permits to make a fourplex and then did the 5th unit fly by night (perhaps at a later date) in order so the property would still be considered residential and allow for better financing possibilities.

I am hoping to view all cases among ranges of dates (i.e 2 week increments). 

I wouldn't say I necessarily do any as Brrrr because there isn't that flexibility to refinance at will so I'd call them more-so value add than Brrrr but end of day, yes they do work out like a Brrr just with determined date for such. 

As used in this Section 18, "Interest in the Property" means any legal or beneficial interest in the Property, including, but not limited to, those beneficial interests transferred in a bond for deed, contract for deed, installment sales contract or escrow agreement, the intent of which is the transfer of title by Borrower at a future date to purchaser.Thanks, I got the impression there was a difference between contract for deed and subject to. 

Freddie has similar intricacies, but also does not require a two year history of receipt; https://guide.freddiemac.com/app/guide/section/5306.4If you can use the rental income to drive the DTI down so that you can reduce the down payment similar to that of the FHA product, the benefits of the conventional option will outweigh the FHA option, as I'm assuming you have a strong FICO based on rate quoted with no points.
