@Landon WrightHey Landon, House Hacking is a great strategy in Houston; you get the benefit of primary interest rate, roommates covering portion or all of mortgage, and cash flowing property once you move out.I am currently doing this in the Heights. 

The biggest value to the seller is often either less capital gains tax on the sale (unless they're seeking a 10-31, then you're out of luck altogether) or a higher sales price with their carrying some or all of the note. 

Your goal in BRRRR is to drive enough appreciation in a short period of time to pull out all or all-most of your original seed capital to reinvest in the next property.

There is a $2 fee for ACH payments but landlord can absorb part or all if desired.

So doing a 1031 into TN investments and then converting some or all into your primary residence later protects that tax bill indefinitely.2.

One thing I always recommend is getting a bank/lender to give you a pre-qualification for a loan using either part or all of the $25K for the DP. 

Payments that you make normally fall into one of 3 buckets100% of the payment can be factored in somewhere on the returnPartial payment can be factored somewhere on the return0% of the payment can be factored in somewhere on the returnHouse-hacking also has considerable tax implications in the event that you want to sell this property.You can potentially defer a portion or all of the gain on the investment property with 1031 exclusion.You can potentially exclude a portion or all of the gain on the personal residence with section 121 exclusion

@Ross Yeager  Yeah, I work with alot of investors and help them with using unsecured lines of credit (credit cards and traditional lines) to fund some or all of their projects.

If you get close to your 1031 45-day deadline, I would consider a DST (Delaware Statutory Trust) for part or all of the funds. (2) We have been analyzing deals and have concluded that if you can reinvest your proceeds in the same calendar year in assets with high accelerated depreciation (mobile home parks and modular storage come to mind) then you may be able to do better to invest directly than with a 1031 exchange.  

Whether you buy 1, none or all 60, make sure the numbers are good. 30% down is too much.
