How to do you first property? 

Keep in mind that inexpensive properties are inexpensive because they are less desirable properties in less desirable areas and attract less desirable tenants.

If I got a home equity loan for Property 1 and used the proceeds as downpayment for Property 2 and then got a 2nd loan for the remaining 75% purchase price for Property 2, when I sell Property 2, can I use the Property 1 loan as part of the cost basis for computing Property 2 capital gains?

.: In a prior post from about 2 months ago, Kerry Malarkey and Nathan Gesner mentioned a small landlord is exempt from FHA requirements requiring the acceptance of emotional support & assistance animals if one of the following is true:"Owner-occupied buildings Properties with four units or fewer that are owned and lived in by the ownerSingle-family homes Homes that are sold or rented without a broker by the owner, as long as the owner doesn't own more than three at once" (Quote from Nathan's reply))https://www.biggerpockets.com/forums/52/topics/1219359-pitbu...Given this, if a landlord does qualify for the exemption, what exactly does this mean? 

I see agents and wholesalers trying to sell properties that are supposedly wholesale, but they sell at retail after it's marked up so much.

Additionally, I would like to attempt to do the process Owner/Builder with subcontracting work out as well as doing some of the work I'm comfortable with (I have some experience with bathroom & kitchen remodeling an am not new to the construction industry).

@Muhammad Kashif Flipping a property in 6–9 months results in short-term capital gains, taxed as ordinary income (up to 37% federally, plus NJ state taxes up to 10.75%).

TLDR: Quicken (quickbook’s little brother) is super easy, cheap, and still overkill for someone with less than 20 properties.

Without going into too much detail, my current situation stems from selling a previous company via partial owner financing, only for the new owner to default on the purchase, leaving me in this position.For traditional financing, I understand I’ll need at least one, if not two, years of solid credit history, tax filings, and other financial documentation.

Sellers may struggle to mentally shift from "owner" to "tenant," which can create challenges with boundaries and property care.Security Deposit:If you’re doing a temporary leaseback, be sure to collect a substantial security deposit to cover potential damages and ensure they vacate on time.
