By the looks of the outside landscaping and minor defects of the house, it does seem like it has been unoccupied...

When you have a strong team (general contractor, designer, architect, landscaper, stager, lender, realtor) these flips move relatively smooth.How many contractors did you use?

From what it looks like it needs to be cleaned up (power wash, minor landscape) from the outside and EVENTUALLY I would like to renovate the units.My question is, is it worth it to purchase this home with the tenants paying the mortgage and taxes (no cash flow) knowing that with renovations I can increase the value of this home.

Some of the the best ways to find off market commercial and multifamily properties is to compile lists from city and county websites if available or through a paid service like List source, Reonomy and CoStar or you can use free resources like Loopnet, CREXI, Craigslist, tax database, brokers, property managers, title companies, environmental consultants, building inspection companies, appraisers, landscapers and other companies that service commercial and multifamily properties and driving for dollars.The real key is in how you approach the owners and then the follow up.

Right now I use a landscaper, and he also shovels snow.

The STR landscape remains tricky to navigate seemingly from town to town.

I have had thousands of mold, landscape and appliance damage/replacements in the last 4 months.

The landscaping and outer aesthetic of the house are not nice at all.How would I calculate how much to invest and how much the property value would go up?

They are growing flowers and vegetable gardens, seeding the lawn and doing significant work on the landscape at all of our buildings.

Ive been in similar spot with leaky basement but was able to dry it out with proper gutter and downspout installation as well as grading/landscaping.
