I have $150,000 in a 403(b). 

ROI is important but I also want to avoid unnecessary headaches so looking for at least a B-/C+ area. 

@Rafael Ramos Recommend you first figure out the property Class you want to invest in, THEN figure out the corresponding location to invest in.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 Class A property in Class D area, what quality of tenant will you get?

Not sure if you need this but something I would recommend for you is this website.https://www.areavibes.com/Use this rating and classification system I have created over time to get an idea of the "Class" for the area - A class B class & so onHere is my rating & classification for each livability score.80 and above A+78/79 A76/77 A-74/75 B+72/73 B70/71 B-68/69 C+66/67 C64/65 C-60/63 D59 and below F Thanks Preston.

And the moment someone discovers toxic chemicals in the ground on a property you own the value will plummet b/c no one will want it. 

Here are the details:**Option A:** - Rate: 6.125% - Credit: $2,300 towards closing costs **Option B:** - Rate: 5.7%   - No credit towards closing costs I'm trying to determine which option is the better deal.

That being said, when they launch their next fund, they are strongly considering a 506(c) offering.https://lastmileinvestments.com/While this is not a list of people I have invested with, I will say a lot of 506(b) operators hide in plain site:- Podcast hosts and guests (talking about what they have done past tense, not current offerings)- The gurus often also syndicate deals- Rise48, per their website, has primarily (if not exclusively) 506(b) offeringsThe thing is, depending on how conservative the compliance attorney is, you can have 506(b) operators advertising like there is no tomorrow.  

Ideally I'd be able to run my own A/B experiments but I imagine there are tons of PM's in here that already have all the data.

I did STR in a duplex starting back in 2017 and managed for others in North Conway, Ive since converted to all long term tenants and happy i did so... unless your property has something unique or a "rare" amenity.... like, sleeps 30, I honestly would not waste any energy on it in the north Conway area. so saturated, and so much big money being invested in the hotels, its tough to match amenities vs cost, and I see travelers trending back towards the hotel style accommodations. granted, for the right price, I'd buy anything and figure out what the best use for it is. use airdna.co for decent data on # of Short term rentals in any particular market. can also identify opportunities. the point of my response.... be careful in STR in any area and always have a plan B. you can change a lot of things about a property, but your cant change your basis!
