You are competing with local investors.

Renting the PropertyIf your parents rent out the home, they have multiple income-generating opportunities: Renting As-Is: A 4-bed/2.5-bath home in a desirable area could command a high rental rate, likely around $2,500–$3,500/month, depending on local market conditions.

Hopefully a local wholesaler can chime in to connect.

Always recommend local (or at least some level of boots on the group).

Then I'd push those factors out if there were no good comps.  2 miles, 6 months.  2 miles 12 months , etc.It takes some local knowledge to know when you're pushing those parameters out too far to be useful. 

Quote from @Devin Peterson: Hey Michael,Local to you in Middletown here I would love to connect and chat more about this one. 

In addition to Turbo Tenant, I would suggest that you have a local Realtor list it for rent. 

Local authorities actually did a great job!

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.

But being a local it seems like the prices are only going higher.
