It is encroaching past your frontage which if I processed a permit to install the service the City wouldn't normally allow, but as an existing condition there isn't any specific issue allowing it to remain.Generally it's not likely that any of your proposed improvements would be immediately adjacent to that PL anyway, so leaving it in place likely presents almost no impact to your proposed development. 

We understand that one property doesn't create financial freedom, but we are committed to growing our portfolio and want to make sure we get off to a strong start. 

In my opinion, getting the license is a pretty big time (90 hrs pre-licensing courses + exams) and money (between courses and MLS access expect close to 1k startup, maybe less for limited broker) commitment if you haven't gotten into real estate yet.

Several options exist, including tearing down the primary residential home and building two duplexes.

It also makes certain capital expenditures, such as roof repairs, can be "lumpy" in that they can be large in one year and non-existent in the next (although they're guaranteed to occur if you own property long enough).  

Absolutely get a title search/commitment.

But you must have a pre existing relationship with them. 506b also has onerous reporting requirements like a yearly financial audit that will run you $10-$20k, so if it’s less than $1M a 506b may not be way to goAnother is a reg a+ offering but that costs $100k+ to setup and requires registering and review by sec.If you want passive investors who are not accredited there are not many options.

I just did 2 multifamily deals with existing tenants, both with estoppels. 

Once enough equity exists in a property, maybe every 5 years, either do a 1031 exchange or a cash-out refinance.My finances:Gross monthly income: approx. $12k, plus an annual bonus that averages to roughly $1k/month (if that can be factored in)Current monthly debts (including mortgage, property tax, insurance, car, child support): approx. $3.5kDebt-to-income concerns:Time for some napkin math for a concern that makes me worry whether this goal is actually possible...Assuming all goes as planned, I worry about eventually hitting a wall where I'm unable to qualify for new mortgages at a certain point due to how the investment properties' mortgages will affect my debt-to-income ratio. 

I am resident of New Jersey and bought my first 4-family (in Somerset) last year at 22 and was initially excited to get the ball rolling, but good deals have seemed to be non-existent since.
