Quote from @Diyan Yap: Have you thought about AirBnB, they can visit/stay with you while they rent it and earn income. 

The current one lasted 8 years and needs to be replaced (as per what our property manager is saying)I heard front loaders could leak, so I typically only do top loaders for rentals.

I don’t have a loan on the property and hold it cash, but, if I sell it would lend the profits as hard money and earn 10%+. 

If they get married it will help her earn SS benefits, etc etc. 

You don't typically don't want this, as this is the lowest evaluation.2.

And, not confident of the earnings/industry in the area to feel good about LTR. 

@Ming HuangRecommend you first figure out the property Class you want to invest in, THEN figure out the corresponding location to invest in.Property Class will typically dictate the Class of tenant you get, which greatly IMPACTS rental income stability and property maintenance/damage by tenants.If you apply Class A assumptions to a Class B or C purchase, your expectations won’t be met and it may be a financial disaster.If you buy/renovate a property in Class D area to Class A standards, what quality of tenant will you get?

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.

Many aren't used to explaining why their services are worth $12,000 (the typical pay for selling an average-priced U.S. home).
