(Note its typically reduced by the percentage, so as an example if you pay 90% - $90k for a $100k loan, and the UPB was reduced by $1,000 - you get a $900 deduction not the full $1,000).But let's take a deeper dive into a LSA and some of the key areas - Specifically the section called "Representations, Warranties & Convenants" For both the buyer and seller. 

While you may have a 2Br that is not for the "typical" sized family, you will have many people also looking to downsize from their larger homes that they are holding on until the summer to list. 

One claimed $100 per day fine from not cutting grass for 2 years to take the $70k excess proceeds.

For our clients, we typically look at the most recent appraisal, county records, or property tax statements from the year of purchase.

Are there typical things in every country or do they all differ too much?

Below are some general notes on DSCR loans:* usually used for single family or 2-8 multi family unit properties (fits your scenario)* must be for investment, non owner occupied (if looking for a product for alternative qualifying solutions for owner occupied there are other products)* can close in a personal name or LLC* usually 80% LTV for a purchase (20% down payment) & usually 75-80% LTV for cash out refis* prepayment penalties vary and are optional, but the higher the prepayment penalty, the lower the rate / options typical range from no prepay all the way up to 5 year prepay and structures vary for how those penalties work (3 year is my most popular by far)* appraisal most likely required and paid out of pocket during transaction* can be used for long term, mid term, or short term rental properties * generally 1%+ is the desired DSCR ratio but you get better rates if the ratio is higher (usually rate breaks kick in at 1.15%+ or 1.25%+) and you can still get the loan done if ratio is lower than 1% but the rate will reflect that (DM me if you wand help learning how to calculate the ratio)* the average time to close is 21-30 days* fees vary lender to lender and product to product, but $1595 underwriting plus title fees is pretty standard* 700+ credit is preferred to get max LTV, but plenty of options if credit falls below that* a typical loan minimum is $75k (have limited options for $50k+) and typical loan maximum is $3-4m (have limited options for $4m+)* 3 months reserves usually required, having 6+ months will usually result in better loan terms, 0 reserves can still get the job done if you go with a program that allows you to use the cash flow as reserves* 30 year fixed, IO, and ARMS available

If you own it outright you could do creative financing, but more than likely selling it the typical way would be easiest/best IMO. 

This is NOT an investment for the typical, conservative investor.

one other tid bit if you own a note and payments stop and you dont start foreclosure in  a certain amount of time ( typically a few years) the mortgage is now unenforceable..

Sounds like the typical student that gets lured into the riches of real estate, but doesn't really understand the amount of work it takes to really get a successful business going.
