I have a friend in Louisiana that's crushing it and may be a good resource for you.

Also, if you goal is to continue scaling, a real estate CPA could be a great resource for accounting and tools like DSCR loans can help your grow quickly, especially for cash-flowing properties. 

@Megan Mason recommend you watch some of the videos from @James Wise youtube channel on S8 evictions.We've been dealing with S8 tenants for over 20 years and they are NOT a cure-all for rent collection challenges.Since rents in Class A & B areas exceed S8 limits, most of your S8 rentals are going to be in Class C/D areas. 

Also, focus on 2 years of job/income stability.Class D Properties:Cashflow vs Appreciation: Typically, all cashflow with little, maybe even negative, relative rent & value appreciationVacancy Est: 20%+ should be used to cover nonpayment, evictions & damages.Tenant Pool: majority will have FICO scores under 560 (almost 30% probability of default), little to no good tradelines, lots of collections & chargeoffs, recent evictions.

I’d also love any recommendations for beginner-friendly books, podcasts, or other resources that are suitable for a teenager. 

@Lisa Eisenhauer thank you for your detailed response Lisa.my hesitancy with titan is that they are a nigerian bank. and my hesitancy with solera is that the are pretty new small bank. given how small banks that have failed in the past, i feel more comfortable with going with someone like chase. here is list from fdic of recent failures: https://www.fdic.gov/resources/resolutions/bank-failures/fai...however, since i ran into problems with chase based on what i described in this post:https://www.biggerpockets.com/forums/51/topics/1150830-bank-...i wanted to know  who i can go with. so i called solera, firstly the person who picked up transferred me to an IRA LLC bank specialist. when my call go transferred, the specialist was i guess working from home and had a crying baby i could hear. that was my first uncomfortable momemt. i don't accept that from a bank. maybe a small retail company or something.secondly, i asked her if you know how an ira llc bank account is set up and i want to make sure it's set up correctly so i have some questions i'd like to understand your process. she right away asked me who is my document provider. and i was like, what is a document provider. she asked who set up your llc and i told her i did that. she said well we usually work with document provider because it's not a typical llc and is set up differently.i assured that the my llc is not an issue, i do  have that set up properly. it is manager managed. i am the manager. my ira is the 100% owner/member of it. then she assumed that my ira is with solera. and i told no, i have it at another custodian, all i want to do at solera is to set up a bank account. and what i want to know is when you open an account at your end, in the bank account who do you put as the owner of llc. she told me well it's a business account that llc owns. and you will be the manager on the account.and i told her, yes, i already know that and that's how it is currently set up at chase. the issue i am asking about is who will be listed as the owner of the llc at your end on the bank acct.. it should be "xyz custodian fbo shaz...IRA" and it should NOT be me. she goes. llc will be the bank owner.i think i had to repeat 3 times that i am  not asking whether or not bank accout will be under llc. i am asking in filling out your paperwork for opening the bank account, does it anywhere ask who is the owner of the llc and if so, who will you put. she goes, oh we dont' mention that anywhere but if you did have your ira with us then we will have "solera bank ..custodian fbo shaz...IRA". 

On paper lay out your scaling and resource categories.

If you elect a PPP shorter than 2-3 years in most cases, the lender is simply going to collect that fee A) upfront as points rather than as a PPP, or B) with yield, meaning a much higher rate.  

I think the issue is going to be more on BP side of how do you collect and monitor this, and is it really worth it, or do you just ban someone for a month for first offense, 3 months for second and lifetime for 3rd...
