I will give you the numbers then tell you mu strategy idea. house purchased for 415,000 in august of 2020 at a sub 4% rate but I treat it as 4% because I am not 100% sure what the rate is (I am getting into contact with realtor soon don't worry)The house could rent for 2,500 per month at minimum and I think I could get 2600-2900 but not 100% sure.It is now on the market for 600, 000 but I think I could get it to 575 since it has been up for a couple months.well 575,000 at a 7% APR is way higher than the rent so I was thinking I could do a seller financed route.

With low cap rates and high revenue and profit, valuations are off the charts!!!...

Is it really possible with current prices and mortgage rates?

I am opening a business in Mexico city (Hair salon) for my wife so get some short term income, Also I am heavily invested in the US stock market but at this time it is not going no where until we have some rate cuts. 

Many HELOC or second mortgages are fixed interest rates and depending on the loan amount, even offer 100% online and no appraisal requirement for issuance.

Long term I anticipate construction costs will generally soften as the high-rate environment continues and stifles development.

They plan activities around the school season.  

My CPA is saying I have to pro rate those expenses for the number of nights that it was actually rented out, but I can't find anything online that confirms that.

Our current renter is likely to be renting for 4 years as she has kids at local school and 4 years would see them through to going to college.We have an old detached 1.5 garage that has functional automatic garage door, and just fits their car....not that they do it very often as I think it is a challenge. 

If you're providing an "up-scale" environment and hope to attract more guests of this calibre (I do; they don't quibble about higher nightly rates and rarely cause problems) then I recommend white duvet covers and wash them after each guest.
