@Carolyn Fuller here is one of the many I have done ( I update them every year or so depending on changes I make to upgrade) CLICK HERE

Make a habit of checking your competitor's listings periodically and when it makes sense for you, make upgrades and listing updates.

Hoping to buy one property by the end of this year, 2 next year and to scale up.Neighbourhood: Class B or C+ neighbourhood.Rehab: Comfortable with cosmetic and upgrades to the property but not a whole tear down gut job. 

Cash Flow: Older Property: Yes, an older home might need costly repairs down the road, such as roofing, plumbing, or electrical upgrades.

Consider property types, low down payment financing options, cash flow calculation, tenant screening, and property upgrades.

It can add a couple of days to upgrade the panel and outlets to a week to rewire.

They are also appealing because they are eco-friendly, again appealing to the younger generations of travelers. 

At the end of the day, you probably should have just flipped the house (but then you probably chose rental upgrades vs. nicer ones so that you won't get as much on the flip either).

Please share your advise/opinion on a possibility to utilizing the space.I’m also thinking about upgrading the basement but not sure where to start.

You are making a grave mistake by looking too far ahead right now, without capital, because that usually means you aren't focused on upgrading and securing your first asset.
