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.

and that was owner occ.. todays rates are pretty normal actually. what you can do if you want though is find a really good HML and let them place a loan for you making 10 to 12% while your wait for things to change to a situation that you feel you want to move forward be more net return than buying a rental thats for sure. of course no tax bene's but there really is not that much tax benefit on one rental.. so just some alternatives. 

New owners are normally at 2 extremes...

Normally, companies keep changing their name after losing all investor’s money.

Normal mortgage rates are in the high 6's now, for a personal residence, and higher for an investment property. 

In Illinois, when an agent does that, there are functions normally expected of the realtor that they are legally prohibited from doing.

So, normalize those values, the state each year will determine the ratio by which the assessment differ's from today's values.

Don't be fooled by the seemingly higher bars in Whitman, the normal line in Grays Ferry is actually closer to or above 250k for the same metrics while Whitman does not break that threshold:Keep in mind, Grays Ferry is significantly larger than Whitman. 

There's a 100 ways to skin a cat, are you looking to build a real estate business or buy 1 maybe 2 deals per year? 

Factoring market conditions at the time of refinance, I negotiated a lower rate and conceded a lower term anticipating rates to normalize in the 4%-5% range by 2026.
