It's something simple but it can be part of first impressions if someone does drive by.You can look toward some very simple and inexpensive staging type stuff, such as trying to make it seem more personal and inviting without making potential buyers feel like they're invading someone's space or subject to someone else's opinionated style choices.

Ok everyone what are your thoughts on this purchase. this property is in South portland maine. asking price was $600k, sell price was $582k seller paid all closing(11K) i also got $3,500 from the seller to pay for some work that was needed. i did get another 1k from seller also for some other stuff. interest rates is 2.875%. i know some dont like this idea but i am 100% leveraged as id i didn't bring a downpayment4unitrents are 1350,1375,1150,1300=$5,175i will be house hacking for atleast a year as its a VA loan but for the purpase of this question i left all the units rents in the calculationexpenses are about 2100 rounded(gas,electric,capx, maintenance and water/sewer)mortgages just under 3000 rounded up(principal, insurance and taxes)so ill be cash flowing about 75 a month. this area is a high appreciating area... or it was who knows with all this covid. part of my thought process on this deal is that my loan will be getting paid down over 10k a year and even if appreciation goes slows there is some room for forced appreciation. what are your thoughts?
