I'm considering adding a bedroom to each in the short term to pump up rent.

I had a place once that didn't have good airflow through the house, I added a few fans to move the air around and it drop temp several degrees.

Particularly around the Springfield Town Center, where 2 million square feet of commercial space and thousands of residential units are in the works by property owner Pennsylvania Real Estate Investment Trust (PREIT), to be delivered by 2026.Below I will go into the reasons why Springfield Virginia real estate market has strong potential for future growth in the coming yearsSpringfield Town Center is Approved to add 2 million Square Feet of Commercial Space and Thousands of Residential Units, Coming in 2026Although many malls suffered greatly during COVID-19, certain malls have begun to make a comeback, such as the Springfield Town Center, which not only is at pre-pandemic levels of visitors and retail vacancy of 4%, but the average time of visit has increased for the mall.

It provides liability protection, and in certain states, you get the added benefit of privacy.

We added cheap square footage by filling in a breezeway which helped to turn an attached ADU from studio to 1-bed, and turn the Main Home from 2-bed, 1-bath into a 3-bed, 2-bath.

@Dalton SmithHello Dalton,My 15 year old HVAC went down today, the motor needs to be replaced it will cost me over $400 and the refrigerant needs to be added that costs another $300 , just the diagnosis costed me over $250.

Examples to kick it off: adding solar panels, vending machines, advertising space, allowing credit card rent payments w/ fee. 

Also, don't overlook the simpler ways of adding value like adding a washer and dryer to a unit or other amenities a deal might not have.

@Karolina Powell..I'm adding my $0.02 as a mortgage broker who does the types of loans you're talking about, works with a lot of investors over the years, and who also has done multiple closes for clients in a tight timeframe/same day/etc. 

@Jason Merchey For more details, check out title 37, chapter 22 of the SC State law: http://www.scstatehouse.gov/code/t37c022.php (emphasis added):(30) "Mortgage loan" means a loan made to a natural person primarily for personal, family, or household use, primarily secured by a mortgage, deed of trust, or other security interest on residential real property or security interest arising under an installment sales contract or equivalent security interest against the borrower's dwelling and: (i) located in South Carolina, (ii) negotiated, offered, or otherwise transacted within this State, in whole or in part, or (iii) made or extended within this State.By definition, you didn't "make a mortgage loan" in the context of the legislation.
