This question can't be answered easily.

@J Shoe I will start by saying consult with a personal attorney and CPA (and have them work together.)Typically people buy in an LLC just to keep their name off the record and for asset protection and operation agreements.As a sole investor a lot of people will buy in their personal name so they can more easily obtain quality financing, and then move the asset into the LLC.A lot of people of California use trusts (DSTs) to hold the asset, so they are not contributing to the problem of over taxation in CA, as CA has a franchise filing fee of $800 every year for each LLC.Just some things to think about, but find the professionals that can tailor a system for you personally.Cheers

if you have the ability to provide these appliances and  can hook them up safely and  easily -   do it and increase the rent a bit  ....if it is  challenging to get these installed / hooked up - forego the  appliances and make  rent lower for the tenants inconvenienece

I imagine its a lot of work and not something you can just do quickly or easily - especially in New York. 

Some can cashflow at today's 7% interest, most can easily cashflow after a 5% refinance.

I usually tell my investor clients that if the building itself will be in a flood zone (not just parts of the lot), it's not worth the investment unless it's a steal and you're able to pay off any mortgage easily if flood rates rise ridiculously (and you can afford to pay for any flood damage, yourself). 

You can easily do this on a spreadsheet, and it will take less time to track than finding and learning new software.

I can rent it for around 1800 near me easily.

If the IRS, for example, looked at a closing where you put $150K down ($100K from a 1031 exchange account and $50K from outside personal funds) on a mixed-use duplex where the value is split 50/50, then they could very easily argue that $25K of your exchange funds went to acquire non-like-kind personal property.

Starting out may be nerve-racking and difficult, but with the right guidance the process can become seamless and easily repeatable.
