I have two options 6.625% 30 year or 6.15% 15 yearI want to invest aggressively in the near future on more propertiesThe loan is only $110k and the monthly payment for 15 year is $563 and $750I will earn 2-3k a month in gross rental revenueThe property is in a declining population areaRecently rennovated, and all major things were relatively recently improved such as plumbing, the roof, a/c, electric, etc.Will require a lot of management as it is rent by the room so I may switch to a normal rental after 10 yearsI'm trying to find what will mathematically net me the most money in the long run.

Deduct NEW property taxes after you buyDeduct home insurance costsDeduct maintenance percentage, typically 10%Deduct vacancy+tenant nonperformance percentage(we recommend 5% for Class A, 10% Class B, 20% Class C, good luck with Class D)Deduct whatever dollar/percentage of cashflow you wantNow, what you have left over is the amount for debt service.Enter it into a mortgage calculator, with current interest rate for an investment property, to determine your maximum mortgage amount.Divide the mortgage amount by either 75% or 80%, depending on the required down payment percentage - this is your tentative price to offer.If the property needs repairs, you'll want to deduct 110%-120% of the estimated repairs from this amount.Be sure to also research the ARV and make sure it's 10-20% higher than your tentative purchase price.As long as the ARV checks out, this is the purchase price to offer.It is probably significantly below the asking price.

My guess is it wouldn't be as critical in an A- or B-class property as it would be in a C-class property. 

Quote from @Montse C.: @Basit Siddiqi @Linda WeygantI believe it’s worth keeping an eye on this development, as this measure is still a proposal and needs to pass through the Spanish Parliament.

For the purposes of simplifying this, let's assume that everything below would happen in Memphis and it would be about C+ class properties.  

Here in Louisville I am looking in C to C- areas.

I already put in $60k down payment on 2 cheap Class C properties Midwest (Indiana) in 2023 - if I had to do it over I wouldn't have bought them.

The cost of entry is low, and cash flow is high.You can find distressed off-market duplexes under 120k and SFH under 80k in B to C-class areas.

roof on, framing done, pool started, rough plumbing done, electrical rough will start next Thursday, A/C install next Tuesday.
