The most advantageous way to raise capital for you would be debt.

If you need money for renovation then maybe your brother is a debt partner and you give him a guaranteed return.

@Dav PohoteThe answer is it depends,Currently you may be much better off at 15 years due to where interest rates are but when they were 3-4% you could have invested the delta between A 15 and 30 year payment and achieved a return better than the interest you were savingIt’s also a personal preference where people like to have less debt and sleep better at night - I am 100% with that being the reason to do 15 %For example for us our primary is 30 year at 3% and we have a rental that we 15 year at 2.5% and reason we did 15 year on it was it matures the year my son will go to college and we did not “need” the cash flow during this time so we were like let’s have it paid off and then it’s cash flow can be used for his schooling or sell it to pay for school.Lots of things to consider and each situation should fit your needs

I graduated college (mistake) last year, I have -$16,000 in debt from the first year I attended.

If your intent it primarily to resell (the definition of a fix n flip) then you can't 1031 it.But that being said, there are a bunch of my clients over the years who have shifted their model slightly so they can get the adrenaline rush of fixing and the tax deferral of 1031.  

Take into account variables like affordability, property taxes, rental regulations, and vacancy rates while doing in-depth market research to find viable investment areas.

Tax Considerations: What taxes should I be aware of for property management services, even if the properties are mine?

A bunch of muni's (tax free), some treasuries, VOOG and maybe 10% to dabble in real estate. 

PPI, the Fed’s preferred measure of inflation, popped up last month, and PCE, CPI and PPI have been resilient to up in the face of the fastest interest rate increases in history and Quantitative Tightening, where the Fed stops buying corporate and government debt to reduce liquidity in the economy and slow financial markets.

Ideally I can find a debt partner who's willing to gap lend those funds for a flat rate return, since the deals cash flow very well, and I'd prefer to retain as much equity as possible.
